This is one of many shorts from Black-American entertainers of the 30s and 40s that is entitled "Hollywood Rhythm: Volume One". It's a wonderful collection of great entertainers that show some of the best music of the time. In this case, what's not to love about "Ain't Misbehavin'"?! It features one of the top Black entertainers of his time, Fats Waller, singing his all-time favorite tune--one that is inextricably linked to him and always will be. And, incidentally, the song is GREAT and Waller's style is wonderful! My only problem is that that's really all there is to this short from Paramount. There is no plot and no other song and it really kept me wanting more. And, because it's so short, I couldn't give it a higher rating.
