Are you thinking of the song that begins "I know where I'm going/And I know who's going with me/I know who I love/But the dear (devil) knows who I'll marry." If it is, there are many recordings of this, including one by Barbara Dane which I listened to just this weekend. The song is available, I believe, on a reissue CD of Barara Dane on Tradition records. They Have a web page. Also, try the music threads here. Good Luck--John
