The DT has a version by Black Bottom McPhail with Scrapper Blackwell on guitar, but that too is related to 'Deep Ellum' or 'Deep Elem' or howsoever it may be spelt. It also has 'Deep Elem' - scroll down to the fascinating and informative notes:
BTW most of the search engine links for 'Down In Black Bottom' are to the Yazoo CD with the Joe Evans recording. There is one with a reference to Ma Rainey's 'Black Bottom', but I have not heard that. Good luck with your search.
