Seems reasonable to me! Interesting history. I can't seem to find any other recordings of the song, so maybe he helped write it for him. I also can't find anything about Johnny Ringo, so that's a dead end.

Other info for the recording:
Mac Wiseman-guitar and lead vocals
Raymond Q. 'Ray' Edenton-guitar
Charles 'Buck' Trent-Banjo
