It exists on discogs in two forms, as an Ernest Tubb release and as a Various Artists release:
It seems like an Ernest Tubb release to me, all the other artists are guests. But it kind of depends on which version of the cover you look at. Based on this one, I can see why someone would enter it as various artists.
I think calling it an Ernest Tubb release fits with this, so I’m entering the change. (Although Wikipedia’s description doesn’t entirely match what’s on discogs, which includes the 2 LP release in 1979. haven’t figured that part out yet).
