Guitars on the Beach could set a record for the U.K.'s biggest ever band, and when they do, they may have a member that has already been in Britain's other biggest ever band.

Paul McCartney may be joining the few thousand people that play a song together to set a new world record.

The song will be 'Rave On' by the late Buddy Holly, played on what would have been the singer's 77th birthday (Sept. 7, 2013)

You can join them too. Just be at the appointed place at the appointed time, and strum along. Then you could say you were in a band with Paul McCartney!
