LONDON -- Don't spend it all in one place, Paul.

London Olympic organizers say former Beatle Paul McCartney and other star performers who took part in Friday's opening ceremony essentially donated their time -- receiving a mere pound($1.57) -- for their performances.

The nominal fee was offered to make the Olympics contracts binding - but pales in comparison to the millions big names like McCartney can command for a stadium gig.

Other performers such as Mike Oldfield, Dizzee Rascal and Emeli Sande are also thought to have received the nominal fee.

Director Danny Boyle's "Isles of Wonder" extravaganza featured British music that spanned generations, right up to live performances from two of the hottest homegrown acts of the moment: grime star Rascal and the band Arctic Monkeys.
