Music for Millions

Six-year-old "Mike" goes to live with her pregnant older sister, Babs, who plays string bass in José Iturbi's orchestra. And the orchestra is rapidly turning completely female, what with the draft. As the orchestra travels around the country, Babs' fellow orchestra members intercept and hide her War Office telegram to protect the baby.
