Mr. Music on AllMovie

Bing Crosby stars as Paul Merrick, an irresponsible songwriter in Mr. Music. Merrick's improvidence and prodigality has made him persona non grata in show business, so his secretary Katherine Holbrook (Nancy Olson) takes it upon herself to rehabilitate her boss. Meanwhile, producer Alex Conway (Charles Coburn) desperately needs a hit show to survive. Conway takes a chance on Merrick, who then enlists several of Katherine's college-student friends to put on a musical revue. All the group needs now is some money--$300,000, to be exact. Mr. Music is enlivened by several guest-star appearances, including Marge & Gower Champion, Dorothy Kirsten, Peggy Lee, the Merry Macs, and Groucho Marx who performs an amusing vaudeville turn with Crosby. Director Richard Haydn shows up in a pivotal cameo role, billed as "Claude Curdle."
