I think the intro explains it all. Jim Lunchick as the Interviewee, Tom penrod as the Interviewer and on bass, Douglas Bland on drums, and of course, John Goldman, who developed the technique of the slide guitar, on vocals.
This could use some remastering, but until that happens, if you have a sub-woofer, turn it down.
Oh, by the way, this is from 1979, I believe. About the same time as the Facebook pics….
