The Grateful Dead used the title "New New Minglewood Blues" for their rendition. That's two "news," so I don't think they expected anyone to think they were faithfully duplicating the original ~ and, as seen above, the lyrics transcribed from the Gus Cannon recording are completely different from the Dead's.

A song entitled "New Minglewood Blues" by one Noah Lewis, significantly different from the Gus Cannon song, is what the Dead actually adapted. It's one of three Noah Lewis songs in the GD repertoire, the others being "Viola Lee Blues" and "Big Railroad Blues."

I think I remember reading somwhere that Minglewood was at one time a thriving lumber camp in Tennessee, sort of a "boom town" with a lot of temporaray jobs, barrooms, whorehouses, gambling, etc. It's not even on the map any more.
