William Thomas Dupree, best known as Champion Jack Dupree, was an American blues pianist. His birth date is disputed, given as July 4, July 10, and July 23, in the years 1908, 1909, or 1910. He died January 21, 1992. Dupree's playing is almost all straight blues and boogie woogie, with no ballads or pop songs, not even blues ballads. He was not a sophisticated musician or singer, but he had a wry and clever way with words: "Mama, move your false teeth, papa wanna scratch your gums." He sometimes sang as if he had a cleft palate and even recorded under the name Harelip Jack Dupree.
