Dizzee Rascal, The Wanted, Rizzle Kicks, Eliza Doolittle, Mark Ronson and Katy B will all perform some songs at a Coca-Cola sponsored pre-Olympics 'spectacular' in Hyde Park on July 26.
The 'gig' will be the culmination of the Olympic Torch Relay, which will also be marked by various outdoor shows around the country.
Emeli Sandé and some terrible indie bands will play Cardiff's Cooper's Field on May 25, Eliza Doolittle and Emeli Sandé again will play Glasgow's George Square on June 28, while Friendly Fires will play Leed's Temple Newsam Park on June 24. The line-up for gig in Birmingham on June 30 is 'TBC'. Perhaps Emeli Sandé will be free.
Tickets will cost £15 but you'll need to register and you can do that here.
