Let me just get this out of the way: the band Black Sabbath is not for everyone. If their choice of band name is not enough to turn off good and proper people, the anecdotes of their excessive living are sufficiently dissuasive. It is an infamy that stems, in large part, from their lead singer Ozzy Osbourne who, for those of my generation, was the subject of playground legend for biting off the head of a live bat during a concert in 1982 (which is not fiction, by the way).
