I've recently did a transcript of how Dennis Puleston sang this song at one of his bawdy song parties in the 1950's. It's more accurate than what I posted above and different than what I found in the manuscript. Obviously the folk process was still very much at work:

As sung by Dennis Puleston in late 1950's and recorded on cassette

Bloody Great Kidney Wiper

The Duchess was a-dressing,
A-dressing for a ball,
When she spied a bloody great tinker
Pissing up against the wall –

Chorus:

With his bloody great kidney wiper,
Yes, bloody great kidney-wee,
And forty yards of foreskin
Hanging down below his knee!

The Duchess wrote a letter
And in it she did say:
"I'd rather be fucked by a tinker
Than my husband any day." (CHO)

And when he got that letter
And in it he did read,
His balls began to fester
And his prick began to bleed. (CHO)

He mounted on his charger
And on it he did ride,
With his penis over his shoulder
And his bollocks by his side. (CHO)

He rode into the parlor;
He rode into the hall;
"God bless!" cried the housemaid,
"He has come to fuck us all!" (CHO)

He fucked them in the kitchen;
He fucked them in the hall,
And then he buggered the butler,
The dirtiest trick of all. (CHO)

He fucked them on the staircase;
He fucked them on the mat;
He went into the stable,
And he fucked the stable cat. (CHO)

He fucked them on the staircase;
He fucked them on the floor;
He gave them such a fucking
As they never had before. (CHO)

And now he's dead and buried;
They say he'll go to hell;
They say he'll fuck the Devil,
But, by God, he'll fuck him well! (CHO)

Cheerily,
