Blues in the Night (1941)

"Jigger' Pine forms a band that includes singer Ginger 'Character' Powell, wife of the trumpeter Leo Powell, and Nickie Haroyen and Peppi. All of them dedicate themselves to work as a unit and to play blues music. The dedication isn't paying off financially and, while riding the rails in a boxcar, they meet and befriend gangster Del Davis. He offers them a job at a New Jersey roadhouse, where Powell falls in love with Kay Grant, a former 'real good friend' of Davis. But when Powell learns that Character is about to have a baby, he returns to her. Jigger tries to make Kay the band's singer and, after this fails, runs off with her. She leaves him with nothing but a nervous breakdown. Back at the roadhouse, after his recovery, Kay shows up, has a quarrel with Davis, shoots and kills him, and plans to take back up with Jigger, who knows better but just can't help himself. While she is waiting in a car for him, along comes cripple Brad Ames, who she put in that condition, and he gets in and drives the car over a cliff, leaving no survivors in the two-passenger crash. The band is back together at the end, still using boxcars as their transportation, but happy playing the blues.
