Those are two great nicknames, and there probably were more.
Champion Jack Dupree led an interesting life, it seems. From the AllMusic bio:
Dupree was notoriously vague about his beginnings, claiming in some interviews that his parents died in a fire set by the Ku Klux Klan, at other times saying that the blaze was accidental. Whatever the circumstances of the tragic conflagration, Dupree grew up in New Orleans’ Colored Waifs’ Home for Boys (Louis Armstrong also spent his formative years there). Learning his trade from barrelhouse 88s ace Willie “Drive ’em Down” Hall, Dupree left the Crescent City in 1930 for Chicago and then Detroit. By 1935, he was boxing professionally in Indianapolis, battling in an estimated 107 bouts.
In 1940, Dupree made his recording debut for Chicago A&R man extraordinaire Lester Melrose and OKeh Records. Dupree’s 1940-1941 output for the Columbia subsidiary exhibited a strong New Orleans tinge despite the Chicago surroundings; his driving “Junker’s Blues” was later cleaned up as Fats Domino’s 1949 debut, “The Fat Man.” After a stretch in the Navy during World War II (he was a Japanese P.O.W. for two years), Dupree decided tickling the 88s beat pugilism any old day. He spent most of his time in New York and quickly became a prolific recording artist, cutting for Continental, Joe Davis, Alert, Apollo, and Red Robin (where he cut a blasting “Shim Sham Shimmy” in 1953), often in the company of Brownie McGhee. Contracts meant little; Dupree masqueraded as Brother Blues on Abbey, Lightnin’ Jr. on Empire, and the truly imaginative Meat Head Johnson for Gotham and Apex. (Continue Reading….)
Here is a discography for Dupree, who fought more than 100 times professionally before becoming a musician.
Above is “Chicken Shack.” Below is “Poor Boy Blues,” featuring King Curtis (whom TDMB will feature in the near future) and Cornell Dupree, who became an important guitarist and I believe is Jack’s son — though I couldn’t verify that on the Web.
