I had the luxury of listening to two other versions, most recently recorded by The Gillette Brothers, Live From The Camp Street Cafe & Store, Big Daddy Records, 2001. Pipp and Guy credit Otto Gray and His Oklahoma Cowboys as their source. A check shows that they recorded the song January 17, 1928 on Gennett 6376.

Anyway, the Gillette Brothers sing FORD as Jim suggests, and for the questionable line they have "Now you might find a beggar who never does beg."

The other version is a bit less common, recorded by Ozark musician Arkansas Red. He also sings FORD but his take on the disputed line is "You might feel wonderful punching a bag."

Other differences are of a minor nature. My guess is that later versions have the same problems, trying to decipher early recordings. I think I'd try to find the Otto Gray version if I could. It has been reissued on BACM 139.
