Is there a music newsgroup that specialises in this type of music? Part of the problem is that this is a folk and blues site so we are less likely (although not totally impossible) to be playing the song you are after.

Try the OLGA site and see if there is a link to a relevant group or site, or maybe you can contact them and ask them directly for leads on finding the answer.

Check back in here and see if anyone knows of other resources, and good luck.
