the McGarrigle sisters recorded a French song "Blanche Comme La Neige" that is wonderfully creepy. They also did "Perrine Etait Servante", which is meant to be cheerful, but Perrine's boyfriend gets eaten by rats.
As I remember it, the English ballad, "The Sad Courting" has it's origins in Eastern Europe, in a song very like "Constantine". I think I found that in "Green Hills of Magic" by Ruth Ann Musick. But don't quote me on that.
