Hey, I'm cool, man! Pop culture is just the weirdest.

Never saw Ozzie live. Saw Black Sabbath, but with a different lead singer. Saw Pink Floyd with Mountain, saw the Allman Bros, the Beach Boys, Crosby, Stills & Nash (then Crosby & Nash and Stephen Stills with--what the heck was his band's name), Joni Mitchell, Judy Collins, Emerson, Lake & Palmer, Queen, Willie Nelson, Billy Idol (opened for Queen), Jethro Tull, the Eagles, Heart, Rush, Pete Seeger with Arlo Guthrie, John Denver, Commander Cody and the Lost Planet Airmen, the Moody Blues, Canned Heat, Iron Maiden and some others.

But I have never seen Ozzie.
