A few posts up, and many years ago, Yorkshire Yankee wrote, "I've heard it performed with an additional verse on the end – which warns against treating women as chattel; did a Google search for it but couldn't find it."

The extra verse was written (or maybe co-written) by Holly Near. A websearch will turn up recordings by her, but not the written lyrics --- on her website, she cites copyright restrictions (she posts the lyrics of songs she wrote herself, but not this song where she just added one verse onto the work of someone else). The extra verse does appear in Rise Up Singing.
