The single, entitled 'I Wish For You the World', was written by singer/songwriter Alistair Griffin and recorded at the famous Angel studios in Islington.

Clare, 50 and from Knowle, worked as a Games Makers in the Aquatics Centre checking tickets, ensuring people were in the correct seats, helping with queries and generally ensuring everything ran smoothly.

She said: “I joined the Games Maker Choir when it was started up in the Olympic Park during the Games. It seemed to me a joyous way of expressing the positive energy generated by our volunteering and a great way to bond with some fellow Games Makers.  We were delighted by the positive response and were then approached by Alistair Griffin with 'I Wish for you the World' and things have snowballed from there.”

Backed by record label Decca, and endorsed by London Mayor Boris Johnson, Olympic gold medallist rower Katherine Grainger, and MP and former Olympics Minister Dame Tessa Jowell, the choir are aiming for the number one spot in the Christmas charts.

The song, which was first played on The Chris Evans Breakfast Show last week, will also feature in BBC Sports Personality of the Year's coverage.

It’s available to download from Amazon and iTunes from Sunday and proceeds will be donated to the British Olympic Foundation and British Paralympic Association to develop and create opportunities for aspiring young people in pursuit of obtaining their sporting dreams.

London Mayor Boris Johnson has thrown his support behind the cause and said: “This song is a great tribute to those feelings of pride, inspiration and goodwill that spread throughout London and the rest of the country during the 2012 Games. I wish everyone involved the best of luck in their efforts in keeping the Olympic spirit alive.”
