It was one of the most watched shows around the world so it came as no surprise that at the London 2012 Opening Ceremony musicians agreed to perform for free.
Emeli Sandé, Dizzee Rascal and Two Door Cinema Club's Alex Trimble received a token fee of £1 to appear in the show.
Arctic Monkeys, who performed two tracks and Sir Paul McCartney also agreed to play at the event for free.
Sandé told the Evening Standard: "I got paid £1 for my work. It's there in print and I know because I signed the contract myself. Mind you, I haven't received anything yet!
"When I do, though, that £1 will be truly special. Part of what made the whole event so special was the volunteers who were paid nothing and even paid for their own accommodation. It shows how important art is."
Dizzee Rascal added: "I feel honoured and humbled to have been asked to be involved. The energy in the stadium was unreal. These opportunities only come by once in a lifetime and to be part of it was an unforgettable experience."
Arctic Monkeys' songs along with other acts including Emeli Sance have climbed the iTunes Chart.
Several tracks that were included in the ceremony were released on the Isles of Wonder compilation after the ceremony on Friday (July 27).
On Sunday's chart, Underworld's 'Caliban's Dream', which was the soundtrack to the lighting of the Olympic cauldron, reached number ten.
