Raymond Scott's 1936 classic, "Powerhouse."
Yep. Probably around the time Jack was just hitting his teens, the brilliance of Warner Brothers team of cartoonists were turning out the classic cartoons which stand the test of time perhaps better than any other.
Around the time Powerhouse was getting a real workout, Carl Stalling was doing a lot of musical direction and arrangements for the cartoons. He especially loved to blend then-popular tunes with classical pieces into the soundtrack of the shorts. Here is one good example. In some six minutes, you'll hear at least one piece every minute mixed in, including Powerhouse. This is the original soundtrack score. Only some sound effects were inserted into this music bed.
