I only knew it from "The Reverend Mr. Black", a kind of story-song the Kingston Trio came out with after Dave Guard left :"He rode easy in the saddle,kind of tall and lean, and first you thought nothin but a streak of mean could make a man look so downright strong, but one look in his eyes and you knowed you was wrong..." A natural for Johnny Cash, if he hasn't covered it already. Or made a TV movie out of it.
