Spartacus, It seems you found the lyrics. Probably here:
The Songs of Woody Guthrie: Farmer Labor Train

I have this song on the following CD:
"Long Ways to Travel: The Unreleased Folkways Masters," Smithsonian/Folkways SF CD 40046, 1994

It's also on a Bear Family record, and here's a quote from it that's on that web site:

"Farmer-Labor Train" is Guthrie's call for farmers and laborers to organize a political party. In June 1948 "People's Songs" felt the song was ideal for Henry Wallace's third-party Presidential campaign. It printed the song as Guthrie sang it in a twelve-page songbook, "Songs for Wallace." The second edition of that book was issued two months later, after Senator Glen Taylor was chosen as Wallace's running mate. The new edition replaces "farmer-labor" with "Wallace-Taylor."
