Rather than a version, this is one of those cases that a full new "species" - a new song family - has evolved from the original. Gid Tanner & His Skillet Lickers, New Lost City Ramblers, most "old timey" artists have performed "Didn't He Ramble." It takes only the chorus of "The Derby Tup" - none of the verses or bawdry or sense if it and produces a whole new song. I'm generally a "lumper," liking to call the same song anything related lineally but I think this one really does go its own way.
