This flamboyant extravaganza tells the scandalous tale of superstar composer Franz Liszts (Roger Daltry) hedonistic life of groupies, sex and music, as well as his rivalry with the scheming Richard Wagner (Paul Nicholas). After enjoying the fruits of his celebrity, Liszt tries to find true love with one of his mistresses, Princess Caroline. The Pope (Ringo Starr) forbids their marriage and Liszt attempts to adopt a monastic lifestyle. The vampiric Wagner marries Liszts daughter, Cosima, and then battles for world domination by unleashing the Viking God, Thor (Rick Wakeman), and his troupe of robot Nazis. The only way to save the world is through Liszt and all of his mistresses in a rocket ship to destroy the resurrected Wagner who has now become the Nazi Antichrist. A freewheeling, outrageous and over-the-top look at the life of the worlds first pop superstar.
