Janet Mitchell is one of 30 singers who have recorded a single inspired by the summer's sporting success, I Wish For The World.
She said: "When I first signed up to be a games maker I never in a million years dreamed that I'd end up making a single and trying to get a Christmas number one.
"Throughout the Olympics and Paralympics I think people were shocked by just how friendly and upbeat all of the volunteers were. Whenever people saw our uniforms they would smile.
"We're hoping to capture the spirit of games with the single."
The mother-of-two added being part of the Games was a 'once in a lifetime experience' that she is 'really proud of'.
The 47-year-old, of Sands Hill, worked as a greeter at Heathrow Airport throughout the summer and met sporting celebrities including Andy Roddick and Lord Sebastian Coe.
The single is set to be released on Sunday and has already been played by Chris Evan's on his Radio 2 breakfast show.
Rower Katherine Grainger, who took home a gold medal at Dorney Lake, and London Mayor Borris Johnson are among personalities supporting the single.
It is being released by Decca which was responsible for last year's festive number one by The Military Wives.
It will raising money for the British Olympic Foundation and British Paralympic Association which help and support athletes who compete in the world events.
