osbourne was the lead singer for black sabbath between 1968 and 1978. he joined again in 1997 for occasional tours. he bit the head off of a bat on stage once. osbourne wrote a song called 'suicide solution' that was heavily ridiculed claiming it was about suicide, which coincided with the words "shoot, shoot" whispered in the song. it was really a tribute to his friend bon scott, lead singer of ac/dc, who died of alcohol poisoning.
