Complete with a final production number filmed in Technicolor, this tuneful musical depicts the highly fictive ups and downs of fabled vaudeville headliners Jack Norworth (1879-1959) and Nora Bayes (1880-1928). After rejecting a partnership with songstress Blanche Mallory (Irene Manning), Norworth (Dennis Morgan) discovers Miss Bayes (Ann Sheridan), who is wasting her considerable vocal talents by working in a honky tonk. Jack convinces the girl to become his partner but Nora's controlling boss, Costello (Robert Shayne), insures that the team is blacklisted everywhere. Despite this setback, the talented husband-and-wife duo finagles an engagement with the 1907 edition of the Ziegfeld Follies and vows the audiences with Jack's newest composition, the lilting "Shine on Harvest Moon." In reality, Norworth met the already famous Bayes at the office of a music publisher and later became one of her five husbands.
