Here's a wonderful video that I watched in my Music in Film class yesterday of Duke Ellington and his Orchestra in Black and Tan Fantasy. Contains such classic comebacks to "Wait, you ain't gonna take my piano, are you?" with "Well, I ain't gonna take your icebox."
That's only part I so another search will need to be done to get the other two.
But even better, here's Louis Armstrong in A Rhapsody in Black and Blue. The racism is outrageous but the music and um...plot? are quite good. Plus Louis has such a great presence on film. Check out his version of "I'll Be Glad When You're Dead."
