A rock 'n' roll parody of "Phantom of the Opera." Splashy, only occasionally horrific spoof in which cruel music executive Williams, much to his everlasting regret, swindles a songwriter. Violence ensues. Not for most, or even many, tastes. Graham steals the film as rocker Beef. A failure at the boxoffice, and now a cult item (small enthusiastic cult with few outside interests) for its oddball humor and outrageous rock star parodies. Williams also wrote the turgid score.
