It sounds a bit like a sailors song to me. The rythem is similar to a sea shanty, and the lyrics also speak about sea (or river, in this case) fairytale. The three daughters represent the three promises for sailors, which are fights (nellie), love (dottie) and salvation (becca). And it is no wonder that their voices are those who lure sailors to wreck and drown.
