You Leave Me Breathless(1938)

A "Screen Songs" short mixing live action with cartoons. The animated section deals with what will be seen on the television sets of the future, i.e., a fountain of youth operating in Turkey, a cow mowing the lawn and feeding at the same time, and other items and then the TV set brings on Jimmy Dorsey and his Orchestra, with Bob Eberle singing "You Leave Me Breathless."
