I can't do this song without crying, so I've never performed it. Guy has a way with the male instincts that is not just Texas macho. I cried when I heard "Let Him Roll" the first time and it wasn't even Guy singing it. In fact, it was before I knew about Guy Clark.
I, too, saw Guy in concert and he did do "The Randall Knife" (although he stuck with the sound reinforcement system). Later I asked him to sing "Let Him Roll" and he said, "One wrist-splitter a night is enough."
Oh, and Barbara, I posted "The Randall Knife" in the Happy Father's Day thread.
