Coincidentally, we were just reading this to my son this evening. Not sure if there's a particular version you're speaking of, however -- the book is just the lyrics to the original song except for a single change - from "...but not so, little boys" to "not so, little girls and boys". And then on the last page, there's a little girl playing with Puff - and a grown up Jackie Paper watching from the sidelines.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
