I did.
Pittsburgh Stanley Theatre (1981)
Ozzy Osbourne and Def Leppard. There may have been a third band but I honestly can't remember.
Ozzy was stoned as usual and didn't sound fantastic but it was a good show. I didn't know anything about Randy Rhoads
so I'm not going to say how great he was but I do remember thinking this guy is pretty good. I had tickets to see them the
following summer but of course that never happened.
