Here you go. (reciting from memory)

Long, long ago in the land of Hushaby
Around about the wondrous days of yore
They came across a kind of box
Bound up with chains and locked with locks
and labelled "kindly do not touch, it's war"

Well the children understood, children happen to be good
and they were just as good around the times of yore
Mother didnt touch it either
sisters, aunts and grannies neither
for they were quiet, sweet and pretty in the wondrous days of yore

But someone did. someone battered in the lid
and spilled the inside out upon the floor
a kind of bouncy bumping ball
made up of all the guns and all
the flags and fear and horror that make war

It bounced right out and went crashing all about
and bumping into everything in store
and whatwas sad and most unfair
is that it didn't really seem to care
just who it bumped, or how, or when, or for

It bumped the children mainly
and I'll tell you this quite plainly
It bumps them every day and more and more
and leaves them, burned and sick and crying
thousands of them dead and dying
For when it bumps its really very sore

now theres a way to stop the ball,
it isn't difficult at all
all it takes is wisdom and I'm absolutely sure
we can put the ball back in the box
and bind the chains and lock the locks
but no-one wants to save the children any more

Well thats the way it all appears
cos its been bouncing round for years and years
In spite of all the wisdom wizzed
since the wondrous days of yore
just put the ball back in the box
bind up the chains and lock the locks
and label "kindly do not touch - ITS WAR"
