Major stars such as Sir Paul McCartney who performed at Danny Boyle's Olympic extravaganza were paid a fee of just £1.
The tiny sum - a nominal fee for contractual purposes - contrasts with the huge payouts they could normally expect for a headline performance.
Others such as Mike Oldfield, Dizzee Rascal and Emeli Sande are also among the stars who are thought to have been paid the token figure.
Big names had originally agreed to play the show in the Olympic Stadium for free, but the inclusion of the £1 figure was to make the contract binding.
It means the star names were paid less than one-twentieth of the cost of the cheapest ticket for the ceremony. Seats ranged up to £2,012 for the best available.
