A long-time favorite:

I have a preference for the alternate take, myself.   Most blues rock musicians inspired by Johnson who emerged in the 1960s never heard the originally released version.  Did they need to?    The first time I heard it was on the Roots Delta Blues compilation that you mention above.   

Several years (about twenty) ago there was a thread about the reissue series from Universal France regarding their magnificent Jazz In Paris releases. Volkher Hofmann documented the release on a web site he created that no longer is active. Discogs has documentation that I have supplemented below at my research site: https://jazzresearch.com/jazz-in-paris/ Jim

Thanks for posting this.   The Columbia 2011 release of the complete recordings was a major sonic improvement over the 1990 Roots'n Blues package.  I don't really hear that much difference between this newly discovered disc and the 2011 release, but I guess that it might be a slight bit sharper and clearer.
