I learned the following from Cyril Tawney in concert. It's not on any of the records I have of him (including Children's songs of Devon) but Devon isn't unlikely. Chris Haslem sings the same set but just gives that he learned it from The Yetties of Dorset. "Rollicking nursery rhyme" is correct. I love it and sing it especially when kids are in the audience and I'm not allowed to sing bawdy material. Kids love it too and get an enormous kick out of it and sing along with gusto. All the more when I explain that this is a song only sung by children and drunken men in bars. Their parents, I say, won't be able to pick up on it. And, of course, their parents can't manage to sing along..

Ask me for it in the (unlikely, I guess) event we meet in a Mudcat Chat thingy

It seems upside down from the above versions.

The Mallard

I have et, and what have I et?
I have et the leg of a mallard.

Leg, legy,
Thigh, thighy,
Shin, shiny,
Foot, footy,
Web, weby,
Heel, heely,
Toe, toey,
Two nippers and all.
And good a-meat was the mallard

But now I am in Debility House
And good a-meat was the mallard

I have et, and what have I et,
I have et the wing of a mallard.
Wing, wingy,
Leg, legy
etc

I have et, and what have I et,
I have et the rump of a mallard.
Rump, rumpy
Wing, wingy,
Leg, legy
etc

Then:        Neck, necky,
        Head, heady,
        Bill, billy,
        Tongue, tonguey.
And good a-meat was the mallard

But now I am in Debility House
And good a-meat was the mallard!

       As Sung by Chris Haslem & Cyril Tawney
