@immatthew: Yeah, the lines separating Country & Western, Hillbilly, Bluegrass, Folk, Singer/Songwriter, etc. are not clear cut. And it was---imo---the emergence of Garth Brooks, Shania Twain, etc. that led "mainstream/commercial" Country music to lose it’s credibility. Steve Earle declared Shania to be "the highest paid lap dancer in Nashville."
Steve Earle does have a way with words.
I probably suffer from the aging process which has an effect on the way I remember "the good old days." Although, at the time, I didn’t think of those days as all that great. And although I listened to it (then) because my choices were limited, (then) I didn’t care for what I think was then mainstream as much as I like it now.
I think back and what I think of then being "mainstream country" strikes me as being more honest than what I consider "mainstream country" now. However, that may not be entirely true. A while back ago I bored and surfing youtube and watching segments of the Buck Owens show (which I used to watch on a fairly regular basis back in the old days) and it reminded me that I was not all that crazy about all of his guests. I am more forgiving of Tanya Tucker now than I was then, but I still don’t like the Hager brothers (I remember seeing them at a state fair in ’77) and I never did like that guy who bore a suspicious resemblance to Buck Owens and that he (Owens) frequently had on as a guest and there were quite a few others that struck me the same way back then.
It could be that the performers/artists that I remember more fondly were the exception and not the rule.
Lastly, I will say that I once went on a binge of watching The Glen Campbell Good Time Hour (not to be confused with The Charlie Manson Good Time Hour) reruns on Tubi, and I completely loved it. I get the impression that Glen Campbell’s "innocent routine" was pretty much a facade, and I thoroughly enjoyed watching the interaction of Jerry Reed (who always looked like he was having nothing but a great time) with anybody (in particular the banjo player, Larry McNeely) and he had a lot of great guests.
