Jesse and the Rippers
On the ABC sitcom Full House (1987-1995), John Stamos played guitarist and lead vocalist Hermes "Jesse" Katsopolis. In addition to the band, he had his own club called "The Smash Club" and he ran the radio show "Rush Hour Renegades."
At one point, he gets so wrapped up in the club that his band kicks him out, so he forms a second band, Hot Daddy and the Monkey Puppets. Then he may or may not have gone solo to sing "Forever," which featured American legends The Beach Boys on backup, prostituting themselves to the absolute utmost. He also sang "For the Times," a song almost identical to "Forever."
