In this musical, a youthful trombonist is thrilled when he is allowed to play with Benny Goodman's Orchestra. Afterward he becomes insufferably egotistical and tries to start his own swing band. It's his girl friend's idea, and unfortunately he fails. He then returns to his old mill job. Fortunately, he is given another chance to play with Benny and the boys. Musical numbers include: "I'm Making Believe," (Mack Gordon, James V. Monaco), as well as "Chug-Chug-Choo-Choo-Chug," "Hey Bub, Let's Have a Ball," "Ten Days with a Baby" (Gordon, Monaco), "I Found a New Baby" (Jack Palmer, Spencer Williams), "Jersey Bounce" (Robert B. Wright, Bobby Plater, Tiny Bradshaw, Edward Johnson), "Let's Dance" (Fanny Baldridge, Gregory Stone, Joseph Bonine), "The World Is Waiting for the Sunrise" (Gene Lockhart, Ernest Seitz), "Mozart's Clarinet Quintet" (performed by Goodman and strings), "No Love, No Nothing" (Leo Robin, Harry Warren), "Rachel's Dream" (Benny Goodman), and "I Yi Yi Yi Yi, I Like You Very Much" (Gordon, Warren)
