......I always heard that as "Don't need no human race" , as it rhymes with "Pretty Face" , unless you've seen it in print as "Human Rights" , which Stiv did'nt seem to care enough about to bring up , until he got involved in the "Sun City'' video.....
Yes , Leadbelly's version is the earliest readily known, but ,I don't think it was the first recorded version. I was listening to it , this evening , in fact. They're still funny lyrics ,anyway , the ones you transcribed.
This Leadbelly record has a few "What THE HELL'S " IN IT , WHICH WAS A BIG DEAL , back then. There's a version of "Whoa Back , Buck " that goes "Who made the Black man , oh , Goddamn", which is'nt in better known versions (Leadbelly re-recorded many of his songs.). First time I heard someone say HELL , like a swear word , was Big Joe Turner "If you did'nt love me , why the HELL did'nt you tell me so?!! ".....Tho' there were a lot of nastier Blues songs on private pressings.
