Bono sustained injuries during tour preparation, I'm guessing during a particularly challenging chest sweep to the floor. Use your knees, not your back Bono! Also, there's that whole turning 50 thing.
While the tour is postponed, Bono will recuperate from his surgery in Munich. Fingers crossed for a successful surgery and speedy recovery! Back injuries are nothing to laugh at (I say, as I make fun of his dance moves.)
