I can't say U2 is my favorite band of all time, but they're on a short list. They're definitely my favorite current working rock band. Bono was involved in a serious bicycle crash a couple months ago, that resulted in some pretty serious injuries. He sustained a compound fracture to his arm, and a fractured eye socket. Three metal plates, 18 screws and a titanium elbow joint, have been surgically installed. Bono said, on the band's website , he may not be able to play guitar again.
