Is this the show John Cipollina appeared on?

I'm looking for a show I saw back in the 80's, and I think it was an episode of this one. There's an episode where the main character walks into a bar, and there's a band playing, with John Cipollina (of Quicksilver Messenger Service fame) playing guitar and singing. Being that Cipollina was from San Francisco (and indeed, Quickilver was one of THE San Francisco bands), and that's where this show is set, I'm thinking it has to be this one, but I really don't remember.
