Eric Clapton will miss the Rock and Roll Hall of Fame concert in New York in order to have gallstones removed. Clapton, 64, "will spend time recuperating at home in the UK and is very sorry to disappoint the fans and the Rock and Roll Hall of Fame," a statement said. Meanwhile, Bruce Springsteen's ability to attend is unknown at this time as he lost his cousin and E Street Band assistant road manager on Monday. The former guitarist of the Yardbirds and Cream was scheduled to perform the second night of the 2 night festival honoring the Hall's 25th anniversary. Other artists scheduled to perform are U2, Metallica, Ozzzy Osbourne, Aretha Franklin, and Annie Lennox.
