The three existing members of John Lennon's first band The Quarrymen will perform at a pre-U.S. release screening of the late Beatles star's biopic Nowhere Boy in Hollywood on Thursday night (30Sep10). The film, which has already been released around Europe, will hit cinemas in America next month (Oct10) to mark what would have been Lennon's 70th birthday. The Quarrymen will also pay tribute to Lennon at his star on the Hollywood Walk of Fame on Friday (01Oct10).
