Ozzy Osbourne

Great singer of the early Black Sabbath (even though technically imperfect, especially live) is still nostalgically praised by many long-time fans and has produced a handful of excellent solo albums. Famous for having bitten a bat, he has fried his brain on alcohol and drugs. It's a shame he lost the little credibility he still had with the reality show "The Osbournes." Today, he is a shadow of his former self.
