Nicest version I've heard in a long time - from the cassette album, Here is a Health
Jim Carroll

There was a frog lived in a well
Fall aye linkum laddie
And a mouse that kept a mill
Tidy Ann, tidy Ann, ditherum di dum dandy

One day says the frog, I'm going to court
With my shoes as black as soot

The horse he rode was a big black snail
Saddle and bridle in under his tail

Frog rode up to the mouse's hole
Rapped the door stout and bold

Arrah missie mouse are you in?
Yes I am, I sit and spin

Arrah missie mouse will you wed?
Will you come into my bed?

Now uncle rat is not at home
Without his leave I'll marry none

Uncle rat he then came down
In his silk and muslin gown

Bring in the table til we dine
Change a farthing and bring in wine

Just as the talk was getting slack
In walked a kittling and a cat

Cat seized uncle by the crown
Kittling knocked wee mousie down

Horsey snail rode up the wall
Says the devil is among you all

Frog he then rode round the room
Just like any sporting groom

In came a flock of neighbour's ducks
Soon devoured the backelors up

Now this whole family went to rack
Between the kittling, ducks and cat
