As soon as I saw the lyrics I recognized the song and could hear it being sung in my head. But I can't remember where I heard it, except that it was long ago and I'm fairly sure it was on a commercial recording, but I don't think it was any of the artists mentioned in this thread. You can hear Savina Yannatou singing it by going to this web page and clicking on the song title Tha Mi Sgith (A Fairy's love story) on the right side of the page.
