A friends mother sang this song, but no one knows the origin. Here are some of the lyrics, and I would like to find the title, the artist, and from where did the song originate.

I saw tonight a lovely dancer
And when I asked her her name
She wouldn't stop to give an answer
But kept on dancing just the same.

As she was dancing on the water
I said I've guessed who you are
You're one of twilight's fairy daughters
Who must have fallen from a star

I appreciate any help you can give me.

Thanks,
