This superb musical biography features Tommy and Jimmy Dorsey as themselves. It’s a good story, but their music is the best part, with each of them leading their own orchestras. There is also one of the greatest jazz sessions ever filmed with piano great Art Tatum, and other jazz greats, Charlie Barnet, Bob Eberly and Ziggy Elman playing along. The film traces the young Dorsey boys drilled by their father who wants them to be musicians rather than coal miners. In a great scene in their first dance hall performance, the boys strike out on their own by picking up the pace with their own style. Father Dorsey is horrified, but when the crowd likes it, as well as the dance hall manager who hires the band on the spot, he quickly changes his tune. Another wonderful aspect of this film is the lovely Janet Blair as the Dorsey’s childhood companion, Jane Howard, who becomes their singer and tries unsuccessfully to keep them from breaking up.
