When I first saw this I thought it was a Fleischer satire of Disney’s Fantasia, but it actually came out three years before Fantasia (1940). I imagine Fantasia was already in some sort of production at that point, so it doesn’t seem unlikely it may have been a satire of the seemingly pretentious and grandiose idea of it at the time, I suppose. This came out before Snow White (1938), Pinocchio (1940), or any of the Disney Features, so the idea of a feature length cartoon probably seemed ridiculous to a lot of people at the time, let alone one that featured animation and classical music.
