Jamie Walters was easily the most famous of the bunch. He parlayed this song into a little bit of a music career, and also was able to pull off the transition to Beverly Hills 90210, where he threw Donna Martin down a flight of stairs. The black guy has a fairly decent acting resume. I remember him being part of Jeremy Piven's non-fraternity in the movie PCU, and he's also the guy in Swingers who says "This place is dead anyway" everywhere they go. And he definitely hung out with Ted Danson on the show Becker.
The red head I recognize as the girl who blew up her microwave in the Christian Slater movie Pump Up the Volume, and I think the blond was on Days of Our Lives in the '80s (which my mom used to watch when I was a kid). After that it goes down hill rapidly. The tough guy lead singer is either Kenny G or Micheal Bolton, and the guy in the Cosby sweater could be Balki from Perfect Stangers, but looks more like his role as Serge on Beverly Hills Cop. And finally, the drummer just makes too many weird "I'm rocking out so hard" faces to figure out who he might be.
