I got this from a recording by Arthur's son, accompanied by Wayne Erbsen.

(D7) I was captured several months a(D7)go little (C)darlin'
(D7)And bound all down in this old Kilby (G)jail
Where I'm (D7)making twenty years little (C)darlin      
bound all (D7)down in this old Kilby (C)jail

Good luck with it...
