The Juicy Fruits

From the 1974 movie Phantom of the Paradise. They start off as a greaser/'50s rock 'n' roll band singing "Goodbye, Eddie, Goodbye" and evolve into a Beach Boys-like surf group. Then they get blown up by the Phantom and die. Archie Hahn did the actual lead vocal. He also had a bit part in Spinal Tap.
