Question: What's the real story behind Iron Man?
Ozzy: Well, it was Geezer Butler, the bass player of Sabbath who brought me the lyric. And what it was about, was a guy who travels through time, and he goes to the future, and he sees the demise of mankind. On the way back to the present time, he goes through this macabre thing, and he gets turned to iron. And he gets so frustrated trying to warn mankind about this impending doom, that he ends up losing it and he starts killing everybody himself.
