Melody Man (1930)
A Viennese composer Von Kemper (John St.Polis), who after murdering both his unfaithful wife and royal lover, flees to America with his young daughter Elsa (Alice Day). Eighteen years later he has become, under an assumed name, a musician in a Broadway restaurant, while Elsa ears her living arranging music for a jazz combo. She and her band-leader beau Al Tyler (Buster Collier) rearrange one of her father's Viennese compositions ...and that leads to the arrest of the elderly composer by the Austrian authorities.
