Naughty But Nice.

Donald Hardwick (Dick Powell) is a stuffed-shirt, classical music professor. His family and small-town music college that he works are of equal mindset. When Don visits his black-sheep aunt in New York in order to find a buyer for his Rhapsody he is exposed to her shocking swing music crowd. His life begins to make dramatic changes after drinking a "lemonade" that turns out to be a Hurricane.
