Has carrying the weight of the entire world on his shoulders finally taken its toll on poor Bono? The first date of U2’s upcoming tour has been postponed following the singer’s hospitalization today for emergency back surgery. According to a statement on the group’s official website, Bono was felled by “an injury sustained during tour preparation†and “once his condition has been assessed further, a statement will be made regarding the impact on forthcoming tour dates.†U2 was scheduled to play Salt Lake City on June 3, but we don’t expect he’ll be jumping out of any giant lemons for awhile. Get well soon, Bono! [U2]
