Stopping and Starting
From inflated egos and clashing personalities to band member deaths and personal hardships, numerous bands, groups, duos, and solo acts have announced a retirement from touring over the years, only to take it all back and hit the stage for another world tour. Ozzy Osbourne has quit before but said that at 74 he's no longer physically capable of touring. We'll see if he really means it this time, but meanwhile, other musical acts continue to hit the road even after calling it quits on touring.
