Ozzy was fantastic in his day. Certainly wasn't pablum or drivel. I heard the song Black Sabbath when I was around 11, and it was like nothing I'd heard before. That was around the time Ozzy was solo. Went ond saw him with Randy Rhoads and that was one of teh best concerts I ever saw--and I've seen a lot. I'm a guitar man myself and I was absolutely pinned to the back wall by Randy.
Another thing I like about Ozzy--read an interview with him once in a guitar mag. "Don't you ever get sick of playing 'Paranoid'?" they asked him.
"I was sick of thta song by the time it came out," Ozzy replied. "But it's not about what I want to play, it's about what the fans want to hear, and as long as the fans want Paranoid, I'll play Paranoid."
And that is why he's stayed ohn top so long.
