Unheralded Newcastle centre Noon delivered a performance of stature just when he needed it as he emerged with a powerful run on the rails from England's congested midfield pack.
Noon has barely been talked about in World Cup terms this summer, yet England boss Brian Ashton will surely find it difficult to ignore the 28-year-old's claims when he finalises his squad to defend the Webb Ellis Trophy.
The world champions' penultimate World Cup warm-up game was all about seizing the moment at a baking Twickenham, and no England player responded in more decisive fashion than Noon.
He might not attract the attention of more celebrated midfield colleagues like Andy Farrell, Mike Catt or Mike Tindall, but his World Cup invitation could be signed, sealed and delivered within 48 hours.
Noon said: "I love playing for England. It drives me, it is a passion of mine, and when I put on that shirt I do my best.
"Sometimes, I make a couple of mistakes, but I go out there and give it everything.
"I believe in my ability, and I believe I am knocking on the door to be in that squad. Deep down, I believe I have got what it takes to play international rugby, and I am just working as hard as everyone else.
"My desire to be in the (World Cup) squad is massive. It is a childhood dream.
"Going into the game, I was actually the most relaxed I have ever been. I believe my destiny was in my own hands, and it was a matter of going out there and playing."
The power of positive thinking has been reinforced to Noon during sessions with renowned mind game experts Steve Black and Dr Steve Peters during recent months.
It is a quality every England World Cup hopeful will require during the next two days as Ashton contemplates his final combinations.
Noon added: "What will be, will be. You can only do your best.
"It is about going out there, working hard and putting everything you have into whatever you are trying to achieve.
"I am more positive now than ever before."
Ashton, consistently non-committal with regard to revealing any selection hints, added: "I thought Jamie played well. He had more than a solid game."
Whether the 25 times-capped Falcons star has done enough, only Ashton knows, although a strong school of thought in the west country points to injury-hit Tindall being picked, despite his last game being four months ago.
If Ashton takes a calculated gamble on Gloucester centre Tindall's fitness - he broke his leg last April and has yet to take part in full England training - Noon could be squeezed out.
On yesterday's evidence that would be harsh in the extreme, and if World Cup warm-up games count for anything, then Noon should be on the September 3 flight to Paris.
