Keith Allen unveils Fit Les Olympics single - video
Renamed Fit Les, the collective best known for 1998's football anthem 'Vindaloo' will release the new track on July 22.
Allen explained to BBC Breakfast that the video was filmed using mobile phones and camcorders, with help from members of the public.
The comedian and actor said that the song is not anti-Olympics, but rather the "whoring" of the Games by corporations.
"The song itself is about exercising the right to be heard. It was born out of the fact that the government have stopped people's right to demonstrate in the lead up to the Olympics.
"I absolutely love the idea of competitive sport, it's just the way it was whored by corporations."
Talking about the success of 'Vindaloo', he added: "I'm not surprised. It's a terrace anthem, it's a folk song.
"I wanted the right-wing supporters to sing a song about vindaloo around the world, it was fun."
