"This Train" and "Good News, Chariot's Comin'" were two staples on the coffee house circuit in the fifties and sixties, at least on the west coast. Variants were plentiful, some with dialect included, many without, probably for the sake of word and melodic flow. The other one I recall from as far back as the forties was "Swing Low, Sweet Chariot," which was a very popular spiritual. I have no idea whether it was actually a composed piece or from the folk tradition, but it received a lot of play.

Chorus:    "Swing low, sweet chariot,
            Comin' for to carry me home.
            Swing low, sweet chariot,
            Comin' for to carry me home.

            I looked over Jordan, and what did I see'
            Comin' for to carry me home,
            A band of angels comin' after me,
            Comin' for to carry me home."

I don't recall the balance of the verses. It might be one of those songs that called for lyrics to be made up on the spot.
