Here are the chords I used at the beginning, and still do. Pretty straightforward:

    D                               C             G          D
I know you rider, gonna miss me when I'm gone,

    D                                        C          G            D
I know you rider, you gonna miss me when I'm gone,

            A7                        G                        A7                D
Gonna miss your sweet papa, babe, from rollin' in your arms.

At times I built a vamped D - C - G - C - D progression under the first two lines and at the ends of all three lines, but not invariably.

Hope the chords appear approximately over the right words ... Bob
