“Why Don’t You Do Right?” was a pop hit for Peggy Lee with Benny Goodman and his Orchestra in 1942 and the song originated as “Weed Smoker’s Dream” on a 1936 record by the Harlem Hamfats (sung and co-written by Kansas Joe McCoy), but it was Lil Green’s moody April 23, 1941, version, revised by McCoy, that became the classic in the blues world. “Why don’t you do right, like some other men do,” she sultrily declared, “Get out of here and get me some money too.” Green, one of the most popular blues singers of the ‘40s, was backed on the Chicago session by Big Bill Broonzy on guitar, Simeon Henry on piano and Ransom Knowling on bass.
