U2 BonoU2 frontman Bono has announced he's fully recovered from emergency back surgery he had in May. In a hand-held video posted on U2's website, Bono apologizes to fans who now must wait an extra year to see the band return to action but promises it will be worth the wait.

"I can sit. I can stand. I can move around a bit. Feeling strong, feeling confident," Bono says as he walks around the recording studio. "And I'm ready -- rebuilt by German engineering, better design I'm told -- and I'm going to be fighting fit next summer in the U.S."
