Carl Lewis singing the National Anthem! Yeah, I remember that. I wanted to kick him the whole time!
Ozzy doing "Take Me Out to the Ballgame" is awsome. It's Ozzy being, well, Ozzy.
As far as live performances that I've seen personally?
-Dokken, twice. Once a Monsters of Rock, Giants Stadium (Van Halen, Scorpions, Metallica, Dokken and Kingdom Come) and once opening for Aerosmith, Nassau Coliseum. Don Dokken's voice just sucks wihout heavy production.
-Spin Doctors, Jones Beach. Free tickets or not they sucked.
-Some local band a Lamor's East in Queens around 1986, peak of he hair band era. This drummer was banging his head and a wig fell off. Too funny.
