I'm with Johnm on this.
Also, the whole picture changes when you consider the Howlin' Wolf/Dixon arrangement. Clearly they morphed the whole tale into a classic "back door man" story!
"When I come out the window, I got no time to lose", and "She's got a mean ol' man, and I'm too young to die". Very funny. You can argue about whether they misunderstood the original story, or knowingly played it for laughs. No way of knowing. Certainly it shatters any imaginary line of "tradition". This is folk music, folks, academia plays only a supporting role where useful; the analogies and connections eventually run out or get ignored.
