"Memphis Slim" is the professional name of Peter Chatman, born to Peter Chatman Snr. in Memphis, Tennessee, September 3rd 1915.
You will find Slim humorously interpolating "Donkey Serenade"
Fragments into his "Scandinavian Boogie".
And worth special attention is the way the initial semi-walking bass figure of the "Fast Boogie" gradually becomes a rolling bass and a "Rocking" Figure.
"Down South" and the double meaning "Big Race" are both obviously the kind of cabaret/social protest that Negro performers were often encouraged to produce in the thirties.
