I Love to Singa (1936)

A very stern owl who teaches 'voice, piano & violin, but no jazz!' becomes a father of four. Very soon, three of his boys turn out to be musical talents in the classical repertoire. However, the fourth isn't into classical music but into jazz. When he keeps singing jazz songs, the father decides that enough is too much and turns him into the street, much to the distress of the mother. While joyously walking and singing through the forest, the young son stumbles across a radio audition day and decides to try his luck. —Marco van Hoof
