All four show just what the Lions means to those involved; all four show just how passionate those who represent the red jersey are and always will be; and all four demonstrate the desire to be respected by supporters from home and critics abroad.
They give us an insight into what goes on inside the pride during one of the greatest sporting shows on earth and they remind us just how unique the Lions brand really is.
And while actions undoubtedly speak louder than words, the passion shown by Jason Leonard, Lawrence Dallaglio, Carwyn James and Warren Gatland act as a reminder that representing Britain and Ireland's elite remains the ultimate achievement this side of the equator.
First up it's three-times tourist Leonard, a man who made 23 Lions appearances and won five Test caps in 1993, 1997 and 2001.
After starting both the second and third internationals in New Zealand in 1993, Leonard arrived in South Africa four years later as a senior hand.
He surprisingly missed out on a starting sport for the Test series against the Springboks after Tom Smith and Paul Wallace excelled on tour but his attitude throughout his second adventure was nothing short of exemplary.
Leonard's philosophy on the Lions was a simple one: it's not about me, it's about us. That unselfish way of thinking was summed up perfectly in his address to the rest of the team in the changing room moments before the opening game of the tour against Eastern Province. His speech that afternoon set the tone for one of the most talked-about Lions tours in history as McGeechan's men picked up on Leonard's call to stay united in adversity and to prove to the world that this particular batch of Lions would be nobody's pushovers.
Jason Leonard understood exactly what it meant to be a Lion
"They underestimate us and they're going to get it rammed down their throats today. It's what they're going to get for the next six weeks. They're going to get taken to the edge every single game," was how Leonard began in Port Elizabeth.
"We're going to blow them away, blow them away, blow them away. There's no doubting this. What you're wearing, people die for.
"I'm sure everybody's played this game in their heads already. You've played it your heads and you know what you want to do. Every single one of us knows what we want to do.
"Think about the contact, think about the first hit. Think about taking the ball in, laying the ball back, quick ball. Think about sizing up your opposite number, cutting him in half.
"Squeeze the arms. Feel that. Squeeze the arms in unity.
"You're playing for everyone back home, everyone who's watching this game, everyone who sent you a message of good luck. That's for us. That's for us. Not one person - for everyone.
"Everyone back home wants you to do well. And it's down to us. No one else.
"Squeeze the arms again. This never gets broken. This chain never gets broken no matter what. We stick together. Whatever sh** happens out there, we stick together.
"Squeeze again. That's it boys, it's there. We want this game. We want this game.
"That's it, stay nice and loose. We don't go inside ourselves. Do not go inside yourselves. We're here, we express ourselves on the pitch - that's what we do. We do not try and cramp anyone's style.
"Let's get this tour going. Let's get this tour off to a big bang, a big bang, a big start.
"What more do you want to achieve? What more do you want to achieve? It's there for us. It's there for us. Squeeze the arms. Squeeze the arms.
"Just 47 of us against all of South Africa. I don't care what happens today as long as you can look at each honestly and say, 'I didn't let you down'."
Leonard's words obviously had the desired effect as the Lions ran out comfortable winners over Eastern Province before taking an unassailable 2-0 series lead against the Springboks.
The reigning World Champions were overwhelming favourites on the first tour of the professional era but Leonard's call struck a chord and the Lions made a mockery of the pre-series predictions.
Our next speech comes from a tour that failed to hit the heights of '97, a tour that isn't remembered too fondly thanks to a 3-0 series whitewash by the All Blacks.
But while results weren't what the Lions wanted in New Zealand, there can be no doubting the passion shown by the players, as Lawrence Dallaglio proved ahead of the defeat to the New Zealand Maori.
The English back-rower's words in the hotel on the day of the game may not have led to a victory but they do give us another indication into how the spirit of the Lions stems from far more than just the 22 men who do battle on the pitch itself.
Lawrence Dallaglio's passion for the Lions shone through on his third tour
"This isn't just a game of rugby - it's our life. We live it, we breathe it," said Dallaglio, who wasn't even in the team on this occasion but was still desperate for the Lions to succeed.
"You've made huge sacrifices to be in this room. Your family have made huge sacrifices, your parents, your coaches, your girlfriends, your wives, they've all made sacrifices to allow you to be in this room. You've got to bring that out tonight. It's not just about you - it's about all the people who make you the person you are, that's what goes into that shirt.
"There's people watching all over the world who've helped put you in this room so, whatever it takes, you've got to find a little bit extra for them. Whether they're alive or whether they're dead, they're there watching and you've got to make it happen.
"I was in a hotel room similar to this four years ago when Graham Henry got up and spoke and the words he said will live with me for the rest of my life.
"He said to me, 'In this part of the world, they do not respect you". He said, 'they do not think you're good enough, they do not think you're skillful enough, they do not think you're fit enough and they do not think you're strong enough, and I should know because I'm one of them.' Not my words, his words.
"And you know what, he's right, they don't respect us. But when they come off that pitch tonight, they're going to know how good we are, they're going to know how strong we are, they're going to know how skillful we are and they are going to respect us.
"Let's get some emotion into this game and let's take it to another level."
Emotion plays a big part in any Lions tour as players, coaches and supporters alike look to harness the unique opportunity that representing four such diverse nations can provide.
But it's not just about turning four into one. Legendary Lions coach Carwyn James knew that forging a victorious squad wasn't about creating a whole new identity. Instead the former Wales and Llanelli boss believed success would stem from bringing the very best out of the four distinct identities that already exited within his tour party.
Rather than look to build something new from scratch by turning everyone into the same kind of Lion, James harnessed the foundations of English, Irish, Scottish and Welsh nationality and told his players to simply be the best versions of themselves.
And by God did it work. James led the 1971 Lions to their only series victory in New Zealand, leaving a legacy that will last forever.
Carwyn James told the likes of Gareth Edwards and Willie John McBride to be themselves
"All you have to do is be your own man. For the next three months all I ask you to do is to express yourselves, not as you would in the office, but as you would at home," was James' way of putting his players at ease before they headed Down Under.
"I don't want Irishmen who pretend to be English, or English thinking they are Celts, or you Scotsmen to be anything less than Scots. You each have a singular and ultimate quality to give in abundance to this team of ours, and you must only express it, both on the field and off it, in your own special, God-given way. And if you do, there will not be remote shadow of doubt that we shall prevail in the huge endeavour we have set ourselves.
"I demand only that you be uncliquey, that in our glorious fusion of national differences and differing temperaments we shall make our whole a vastly more potent force than the sum of our parts.
"Let you Irish be the supreme ideologists off the pitch, and on it fierce scrappers like Kilkenny cats.
"Let you rejuvenated English stiffen those upper lips, and then simply continue to be superior.
"Make sure, you Scots, that your conservative traditionalism of history, strong and dour, is now oiled by your nation's marvellous, new-found radicalism.
"And you Welshmen of mine, well, just continue to be cocksure and bloody-minded in your new Triple Crowning triple-clowning arrogance."
Perhaps fittingly given the fact that he will be the voice of the Lions in 2013, the last word in our Power of Speech series goes to Gatland.
The current Wales supremo may be a New Zealander but he knows all about the inner workings of what makes the Lions tick.
Gatland was an assistant to McGeechan when the Lions toured South Africa in 2009, a tour on which the squad earned a vast amount of respect both at home and aboard.
But picking up a few pats on the back for their sumptuous style of play and for running the World Champion Springboks so close in the first two Tests wasn't enough for Gatland. A win was all that mattered in the final rubber at South Africa's spiritual home and Gatland's plea to his players just moments before kick off set the platform for the Lions to head home on a high.
Warren Gatland's words inspired the 2009 Lions to finish with a flourish
"We're in Johannesburg, South Africa, at Ellis Park. Earn some respect, yes. But the only way to earn respect against these ***** is by beating them. It's the only way. No matter all the nice things they say, you've got to beat them. We do it out there, on the scoreboard, " was Gatland's war cry last time out.
"Yes, we've improved from week one, from Test one and Test two, but the sign of character is how we perform and what we do out there today. Nothing but a win is acceptable.
"For those guys wearing the jersey for the last time: remember it."
