The Fabulous Dorseys

The movie tells the story of musician and bandleader brothers Tommy and Jimmy Dorsey (played by themselves), from their upbringing in Pennsylvania coal country to modest musical beginnings in small venues, to eventual radio success. Their fiery temperaments cause them to clash with each other often, eventually leading to a split and them each forming their own orchestras, after which they find even more success. Also starring Janet Blair as a childhood friend, singer, and peacemaker between the brothers, and William Lundigan as a composer and piano player for the band, as well as love interest for Blair.

Tommy the trombone player and Jimmy the saxophone player are excellent musicians but horrible actors. Thus the script focuses more often on the fictional characters played by Blair and Lundigan, neither of whom are much more compelling than the Dorseys. The viewer also begins to notice that not much of dramatic interest happens in the Dorseys lives other than them bickering like brothers do, so the only saving grace is the music, much of it performed by singers and musicians of the day playing themselves in cameos. I'm not familiar with many of them, but the music they perform is fine, and I'm sure will be appreciated by fans of the style.
