Gallstones have forced Eric Clapton to pull out of this week's Rock and Roll Hall of Fame 25th anniversary concerts. Clapton was to have played on Friday (October 30th) at New York's Madison Square Garden on a bill with U2, Aretha Franklin, Ozzy Osbourne, the Kinks' Ray Davies, Jeff Beck, Buddy Guy and others. According to a statement, Clapton "will spend time recuperating at home in the U.K. and is very sorry to disappoint the fans and the Rock and Roll Hall of Fame." Concert organizers are relieved, however, that Bruce Springsteen and the E Street Band will perform at Thursday's (October 29th) concert despite the death of his cousin and assistant road manager Danny Sullivan earlier this week. Springsteen and company did cancel a planned show at Kansas City but have confirmed that they'll play the Hall of Fame show as scheduled.
