There's that bit from Lizzy Wan:

There is a child between my two sides,
Between my willy and eye...

And of coarse:

I went to market to buy a cock
And me cock did very well please me
Every time I fed me cock
I fed him all under a tree

And me cock went cock a cock a cock a doodle doo
And after every farmer's cock did my cock crow

Don't forget Celia Learning on the Spinet to Play, though you'll need three voices and a lot of practice.
