Saw him do a Black Sabbath show - w a couple Ozzy solo hits thrown in for good measure - at the Hollywood Bowl about ten (?) years ago.
Excellent show, w the always-spooky opener War Pigs to kick things off.
Yep, Ozzy's a trooper...
btw, like Alice Cooper whom if you've never seen you owe yourself... even my 77 year old mom liked the Cooper show; her comment, "That was incredible."
