Well, here’s a blast from the past if I’ve ever seen one! Someone has uploaded footage of Pennywise playing a show in Hollywood way back in 1993. Jim Lindberg was absent from the band at the time, so Jason Thirsk handled lead vocal duties and now-permanent member Randy Bradbury filled in on bass.
Sadly, the show ended up getting shut down by the cops when the band was only 16 minutes into their set. It’s an awesome 16 minutes, though and footage of this lineup playing live is pretty hard to come by.
