Yes, GUEST,rick, the lyrics in the digitrad are not the lyrics Blake wrote but considering the notes about where this song was first heard, this sounds like a case of a performer (or more than one) moving the song along via word of mouth and singing what they think they heard. (Or they decided to make a few changes that they thought would help the song.)
The lyrics you've posted are the same lyrics that Robert Earl Keen, Jr. did in his version, which is where I first heard the song performed. Since I've got this thing about taking songs that I really like and making my own modifications to fit a different geographic area or era, I've focused on doing a version that deemphasizes the Western-ness of the song and reset it to my home county in Mississippi. That makes the song appeal more to locals when I do a song set for the local historical society. Since I'm not modifying the song for purposes of creating a separate arrangement or striving for a copyrightable performance version, I figure no harm's been done. (Plus I don't earn any money when I perform for the historical society, it's totally a volunteer effort.)
It's a doggone good song any way you do it.
