In Chicago for a charity gig, bandleader Benny Goodman chances to hear the hot stylings of an impoverished young trombonist (James Cardwell), and offers him a job on the spot. Though the kid is initially thrilled, will his snowballing ego─and the prodding of his pushy girlfriend (Linda Darnell)─only result in sour notes? Sizzling swing musical co-stars Jack Oakie, Lynn Bari, Allyn Joslyn; score includes "I'm Making Believe," "Ten Days with Baby." 75 min. Standard; Soundtrack: English Dolby Digital mono.
