I just looked at it, too, the error looks to be a computer error of some kind.

The first verse: (Taken from the singing of the Cartwright Brothers on Yazoo 2022, When I Was A Cowboy, Vol.1)

Come all you Texas Rangers, wherever you may be
I'll tell you of some troubles that happened unto me
My name is nothing extra, so that I will not tell
And here's to all you Rangers, I'm sure I wish you well
Twas at the age of 17, I joined a jolly band . . .

Listening further to this version, I noted that it is not quite the same as that in the DT. Of course, it is possible to find any number of variations if you look hard enough, and who is to say that any one version is any more correct than any other. That is part of the folk process.

I did note that the words in the DT were taken from the book Southern Folk Ballads, written by Dr. Bill McNeil of the Ozark Folk Center. Then I checked and found 10 other songs from the same book.
