Thanks to everyone!!

This thread solves a mystery for me (wish Vaughn was here to read it).
Lawrence Older - Adirondack traditional singer and incorrigible song sponge - learned this song from Jean Redpath. Both frequented Caffe Lena regularly many years ago. We learned it from Lawrence and his wife Martha, and taught it our own kids and to generations of kids and parents at Pinewoods Camp as a "going to bed song". It is now in our grandkids' repertoires.

I'll do a midi tonight or Monday. No guarantee that it is anything but our version, but I think it may be close to Jean's. Heck, it was only forty years ago.
