Looking for the name of a movie from 1930's or 40's.

Daughter tries to help her father and his unemployed musician friends get heard by a famous conductor. She eventually is successful and conductor hears how good these 'local' New York musicians can play. Then takes them on tour with him. (I believe this was the young actress' only movie as she then moved to England, never to return to U.S.)
