Snow White Gone Wild

In the name of preservation of the performing arts, I give you this. It's maybe seven minutes long, and about four minutes in, you will see the rotoscope animation of Cab Calloway (as Koko-- Betty Boop's sidekick) and hear his 1933 rendition of St. James Infirmary Blues. And check out that animation! 1933? Pot was legal then, right?

According to Wikipedia The film has been deemed "culturally significant" by the United States Library of Congress and selected for preservation in the National Film Registry.
Not only that, it's fun as all get out to watch.
