Come Sisters Come (Edge of the Night)

I've been given this song under two different names and unfortunately I have no source for it. If you know a songbook where I can find this song, please let me know. Thanks very much to Megan Burns and Megan Davis, who both sent me this song.

Edge of the night
A campfire's light
Come sisters, come

Magic of song
A place to belong
Come sisters, come

Warmth of a fire
Warmth of a friend
Come sisters, come

When days have passed
To the memories that last
Sisters, come back again.
