This is Royce Robinson--from Gastonia--- with a second opinion. If you ever perform the Foster/Ashley version of the song, I am pretty sure it is the Rayless chain. As I read the lyrics it seems to make more sense than "railer's chain." Particularly when you visualize the bay rum hounds pretty close to the Rayless chain. Also on the good for you stomach line. Since it is good for the stomach, think I'll get a little more!!! From what I have read about Dave McCarn, his version was from personal experience.
