Deanna Durbin and Leopold Stokowski - '100 Men and a Girl'

In this 1937 comedy with music, Deanna Durbin persuades world-famous maestro Leopold Stokowski to conduct an orchestra of 100 unemployed musicians which includes her trombonist father, played by Adolphe Menjou. We see the opening credits, during which Stokowski conducts a much abridged Tchaikovsky 5th Symphony finale, and the closing scene where the unemployed musicians and Deanna bring the movie to a close with a delightfully spontaneous and unrehearsed Verdi number.
