It's been rumored for some time that Paul McCartney might have some involvement with the London Summer 2012 Olympics. Now the onetime Beatle is coming clean on the matter.

He told BBC's 5 Live radio station that he has indeed been booked for the opening ceremony and will be the final performer for the event. According to Australia's Yahoo News, McCartney will wrap up the opening ceremonies, which are being constructed by 'Slumdog Millionaire' director Danny Boyle.

The event has been titled 'Isles of Wonder,' but specific details surrounding the production have been kept under wraps. A cast of over 15,000 people are expected to be part of both the opening and closing events.

In addition, Duran Duran, Snow Patrol, Stereophonics, and Paolo Nutini will play an Olympic Games opening concert, with each band representing one of the U.K. factions. Duran Duran will perform for England, Snow Patrol for Ireland, Stereophonics for Wales, and Nutini for Scotland.

Blur, New Order, and the Specials have all signed on to take part in the London 2012 Olympic closing ceremony.

The Olympic Games run July 27 through August 12.
