They Shall Have Music

They Shall Have Music is a 1939 musical film starring famed violinist Jascha Heifetz as himself, Joel McCrea, Andrea Leeds, and Gene Reynolds. A young runaway finds his purpose in life after hearing Heifetz play, and the kindly master of a music school in financial difficulty takes him in.

Unbeknownst to Lawson, the school which does not require tuition fees is in financial trouble. The schools sponsor has died, and bills have gone unpaid for months. All of the musical instruments are rented from a stingy music store owner ironically named Mr. Flower Porter Hall. Flower assigns one of his clerks, Peter Joel McCrea, to collect payment, but Peters girlfriend is Lawsons daughter, Ann Andrea Leeds, so he does nothing. When Flower finds out, he fires Peter and goes to confront Ann.Frankie overhears Peter and Ann discussing the situation, and organizes a street band with some of the other students to raise money. They set up right next to a concert hall where, according to clever Frankie, people will like us. When Jascha Heifetz comes out of the hall, Frankie recognizes him and tells him about the school and the fund raising concert they have scheduled. Heifetz is impressed with Frankie and the story and offers to send a film of himself playing. Later, when Flower and the other creditors show up to collect payment, they get the mistaken impression that Heifetz is the schools new sponsor. Peter plays along to buy time, and even claims that the violinist will perform at the schools upcoming concert. ........
