Growing up in post war England, I only knew the bawdy version for years before I realised there was actually a clean set of words. We would hear ex-soldiers singing these songs when they'd had a few and the women weren't around and of course they did the rounds at school. The words we sang as horrible little pre-pubescent youths were as follows, with some censorship that you can fill in yourself. Forgive my sensitivity.
Three German soldiers crossed the Rhine
They f***d the girls and drank the wine

They came upon a wayside inn
They pissed on the door and kicked it in

The innkeeper had a daughter fair
With little white tits and golden hair

They tied her to a rusty bed
And F***d her till she was nearly dead

They took her down a leafy lane
And f***d her back to life again

It's not exactly Shakespear, but if I can remember it forty years on, I must have heard it a lot.
