Jesse and the Rippers is a band that Jesse Katsopolis formed. In Japan, they are loved and one of their songs is #1 on the charts in there.
After Jesse is kicked out of the band for his commitment to his family, he is replaced by former Brady Bunch star Barry Williams (and the band is renamed Barry and the Rippers). They achieved a hit song "April Girls", which is loved by everyone in the Tanner household, much to Jesse's chagrin. Jesse later forms a new band called Hot Daddy and the Monkey Puppets.
On July 19, 2013, Jesse and the Rippers reunited on Late Night with Jimmy Fallon. They performed a medley of covers including the Beach Boys' "Forever", Elvis Presley's "Little Sister", Chan Romero's "Hippie Hippie Shake", and ending with the Full House theme "Everywhere You Look". Bob Saget and Lori Loughlin made cameo appearances.
Fuller HouseThe Rippers made an appearance at the going away party in the premiere episode of the spin-off series Fuller House. As D.J. goes around the room noting all the family and friends that are "leaving," she turns to The Rippers and quips "I hope you're leaving..."
The guys then play "Forever" and Jesse sings it presumably (and if Jesse has it his way) one last time. They then begin to play "Wild Thing" as Danny sings, but everyone leaves.
