The Fabulous Dorseys
Growing up in a coal-mining community in Philadelphia, Tommy and Jimmy Dorsey (playing themselves) are encouraged by their father, Thomas (Arthur Shields), to study music. The highly competitive siblings are soon playing with their father's band. As grown men, the Dorseys begin touring with their own ensemble, with childhood friend Jane Howard (Janet Blair) on vocals. Despite their rising success, the bickering brothers have a falling out, and Jane schemes to reconcile them.
