At this site, I found many different versions of the song "The Twa Sisters", "Binnorie," or "Cruel Sister." I'm curious, though; an author based a short story on this song after she heard one variation on it mention *three* sisters. Does anyone know this version? Also, for those of you who run Mudcat, I noticed that you didn't have the music for "Cruel Sister." You could try looking into the group Pentangle - I know they did a recording of it, but I'm not sure how true to any traditional melody it is. Good luck!
