Ahhh...I'm not a bit surprised at that story, MtheGM. So many of the themes are common to people down thru the centuries. Not nearly as many sisters pushing each other in the river, perhaps....but men fighting over a girl? Jilted lovers getting revenge? A girl running away with charismatic strangers?
All it takes is a couple of name changes and someone hears the song and says: "Why, sure....I think my daddy knew them."
