This is a beautiful musical short that is frowned on these days because it features caricatures of Stephin Fetchit, Cab Calloway, Fats Waller, Louie Armstrong and others. It's really too bad, because the jazz is great and it's a wonderful piece of animation. Unfortunately, the prevailing attitude these days seems to be that animation is for kids when the reality is these shorts were made for adults and children both. You'll have to dig to find this, but it's worth the time and effort. Most highly recommended.
