This very early Warner Bros. Short has two claims to fame -- it's on the "Censored 11" list of cartoons United Artists ceased distribution of in 1968 because of their crude racial depictions, and it borrows scenes from two far more well-known cartoons -- the famous "Steamboat Willie" (1st Mickey Mouse) and the horror classic "Skeleton Dance," both from 1920s Disney.
And while this toon is mildly enjoyable but rather nondescript, the music is incredible. And, as far as I can tell, made especially for this cartoon. I need to do more research into this because this seems hard to believe, but I can't find any evidence of this song having existed outside of this cartoon, unlike the songs used in many 1930s WB toons. It sounds so authentic and lively and lived-in, like it came straight from some obscure country blues 78 on Paramount from the decade before.
