Superman Annual #1960

Jimmy's cousin Jerry is the famous \"Rock 'N' Roll Olsen\", but is down with chicken pox and must cancel his concerts. Jimmy agrees to disguise and lip-sync to a tape recorder hidden in his guitar. But the recorder triggers his signal watch and makes Superman dance rock'n'roll across town. Superman fouls up a charity ball, gets thrown out of a girl's calisthenics class, and can't catch \"The Earl\" and his gang from committing robberies. And he's lost his dignity!
