There's something depressing about URGH! Not sure what, exactly, I haven't seen it in probably 20 years, but I had a tape of it and just remember wanting to kill myself every time I put it on. Not because of the music, there's just something about the vibe, baby.
My old man dragged me to a Roy Clark concert when I was a kid (1969 or 1970) and it was incredible. I think he played every stringed instrument known to man that night, and he was great on all of them. I would have rather been seeing Alice Cooper at that point, but Clark made a big impression on me, and I can still remember bits of that show.
