Juke Box Jenny

Donald Douglas runs a losing classical music label that is subsidized by the mother of his fiancee, Harriet Hilliard. One evening his old fraternity brothers get him drunk and convince him he asked a bunch of jazz musicians and Iris Adrian to come up -- Miss Adrian tells him she and he are married. Before she can put the distracted guy out of his misery, he has Ken Murray making her a star of the juke boxes, while trying to cover up the situation like a cat on the tiles, by taking recordings of Miss Hilliard's voice singing old songs, backing them with swing music and putting them out under Miss Adrian's name.

It's a paper-thin nonsense plot that doesn't quite cover some good music, including Charlie Barnett and Wingy Manone. It's basically a series of musical sets with an annoying plot about snobby classical music lovers who don't think jazz is real. Surely by the 1940s, this was settled, and they could have trimmed that aspect of the plot to fit the times.
