Amazed to see my wee song all over the place. Thanks to my lovely friend Alison Duncan.
Here it is.
Last line is an instruction "start off with a Cuddle", not "you start off.. " Miss that "you". it sings better.
Here's the gen anyway:
Cuddle (against the War)

Some folk say that only nuclear arms will keep us safe,
others that only conventional arms will keep us safe.
The ONLY arms that will keep us safe are fixed to our shoulders,
and we got them for cuddling with.

A friend reported some years ago that Cuddle was now "in the tradition" as he heard a new version at Sidmouth Folk Festival. It went:   "Piddle, piddle, piddle against the wall.... "

And Newcastle's lovely singer Di Henderson   has been known to sing
"..... Escalation could be luck
Start off with a cuddle, end up with a ...... "             ( now what was she going to say!)

                title: CUDDLE

                Chorus:
                Cuddle, cuddle, cuddle against the war
                Use your arms for cuddlin, that's what arms are for
                Escalation could be bliss
                Start off with a cuddle, end up with a kiss

                Cuddle a Russian, peasant or Czar
                And he may show you his ... samovar
                They say the Russians answer Niet
                I've never had that answer yet !

                Cuddle a Frenchman from Gay Paree
                Go and sit upon his knee
                Run your fingers through his hair
                And leave the rest to Laissez-faire !

                Cuddle and Injun, do it with verve
                Break down that Brave's reserve
                Get into a big Pow-wow
                I'm sure that he will show you "How !"

                Cuddle Australian, a wizard from Oz
                Lie on the beach with Santa Claus
                Rub his back with amber oils
                And wait until his Billy boils !

                Cuddle a Scotsman, he's Clydeside built
                Ask what's worn beneath the Kilt
                "There's nothing worn North of the border,
                 Ma dear, it's all in working order !"
