Ian, as far as I know the Opie book is still in print. The Opies were collecters of playground lore among many other things. They collected jumprope rhymes, street chants and taunts, and much more, on both sides of the puddle. I owe a lot to them in my appreciation of the hand-clapping games at the back of the bus on field trip days- sometimes I bring a tape recorder! Hey, Joe Offer- there's a field for you to collect in!
