Well, I just posted my own question to this board yesterday, and by coincidence (?) I think I happen to know the answer to this question. Consider it a payback for the help I've gotten so far (thank you Dale and Joe).As I said in my question, I'm the farthest thing from a folk expert, but I believe that the artist/album you are thinking of is Sally Barker, "This Rhythm is Mine" (1990). I think it can be special ordered from Borders.com.
I had searched for info on this song, too, after it was given to me, untitled and unattributed, on a tape. I found it once and misplaced the note; your message prompted me to search again. Great lyrics, beautiful voice.
Re: the comments from Sam and AndyG, I note that Sally was a founding member of the Poozies, and has recorded songs with Pete Morton, as well.
I hope this helps.
