For the last few days, wounded, sick and injured servicemen and women from across the world have been competing in this sporting competition in London, and now it's set to all finish up on a high with a whole load of stars performing at the closing ceremony in Olympic Park. Clare Balding and Greg James present performances from Foo Fighters, Kaiser Chiefs, Ellie Goulding, Rizzle Kicks, Ryan Adams, the Vamps and Diversity, as well as former soldier James Blunt and the Military Wives Choirs. There will also be a medallion ceremony to pay tribute to all the inspirational participants.
