Animation and music have gone hand in glove since the sound era and probably beforehand. While Warner Brothers and MGM featured music prominently, Lantz and Fliescher went a step or two further, by creating series built around music (mostly jazz) and the Betty Boop shorts featured music frequently. This short is one of the best they did. The mix of the animation and the Cab Calloway song is fantastic! All the studios used music in the creative process for their animation, with varying success. Warner Brothers did so because they saw a way to utilize the large catalog of songs from their film library, while Disney saw the potential revenue streams music would afford them. Whatever the reason, some great cartoons were made, including quite few Betty Boops. This is a must see. Most highly recommended.
