I still haven't listened to the album, but Desert Dancer said it was by John Allison and Claudine Langille. The site DD linked to has a link to MP3.com which calls the song traditional. It's probably the same John Allison who recorded my album, so it's probably the same song.
There's another song on the album about Goody Nurse. I haven't heard for a while, but I remember it being a lot more in touch with the truth
