Three of the Beatles’ children have united on a new song. Ringo Starr’s son, Zak Starkey, confirmed that John Lennon’s son, Sean Ono Lennon, and Paul McCartney’s son, James McCartney, provided vocals on his supergroup Mantra of the Cosmos’ upcoming single “Rip Off.”

Zak Starkey isn't the only one who has had enough of The Who. In a new Rolling Stone interview posted on Monday (June 16) the veteran session and touring drummer who was fired, rehired and then fired once more by The Who in a head-spinning span of several weeks earlier this year opened up about his current relationship with the band and how his dad feels about the tabloid tussle.
