Golden Eyes was inspired by Andre Norton's Witch World series. Later Mercedes Lackey turned the song into a short story called Werehunter. You can find the story in her anthology called Werehunter, along with some other wonderful stories, or you read it on firebirdsart.com, where it has been reprinted with permission from Baen Books.
I prefer this version over the one on The Horsetamer's Daughter. The melody is the same, but the arrangement on Magic, Moondust, and Melancholy captures the emotion better in my opinion. The guitar and flute balance well with the vocal and give the song a softer ambiance. I'd almost call it a quiet elegance, though that may be an odd description for a melancholic song.
