The lyrics given by Judith Bard are those of our family's version of, "The Old Woman All Skin and Bones." Most USA kids know it because it's now in almost every elementary music book in the country. I recorded it on a very early record (in the '50s?), and recently it has been recorded by Raffi. When I sing it in concert nowadays, all the kids eyes light up and they help sing the chorus- but they still jump at the shouted "BOO!" at the end. Trick is to hold off a few moments so that they don't know when it's going to happen. I'm an old lady now, but it's still the best Halowe'en song I ever heard!
My Mom made up a verse; Granny Catty contributed another. There are two more verses not given by Bard.

OOO-OOOO=OOOO-OO- BOO! Have a great scary Halowe'en!!!    Jean
