"Music in the Air" - The boy plays the piano while the girl plays the violin. They both sing.
They appear to be using the songs of but one publisher, disregarding whether those numbers fit their style, voices or act. The double number near the finish fits neither of them. The act has a chance on the small time. What "Music in the Air" stands for is left to the imagination.
