This past weekend The Edge performed alongside Paul McCartney at a fundraiser event recognizing the tenth anniversary of Barretstown, an Irish children’s cancer organization.

The Beatle and U2 guitarist offered up a version of Buddy Holly’s “Peggy Sue” to the 300 guests gathered for the organization’s gala ball. (McCartney purchased the rights to all of Holly’s music in 1976.) The guitar McCartney used during their performance was later auctioned for EUR 55,000.
