Jollity Farm

There's a farm called Misery
But of that, we'll have none
Because we know of one
That's always lots of fun
(Ha! Ha!)

And this one's name is Jollity
Believe me folks, it's great
For everything sings out to us
As we go through the gate

All the little pigs, they grunt and howl
The cats meow
The dogs bow wow
Everybody makes a row
Down on Jollity Farm

All the little pigs, they grunt and howl
(Grunt! Howl! Grunt! Howl!)
The cats meow
(Me-ow! Me-ow!)
The dogs bow wow
(Ruff! Ruff! Ruff! Ruff!)
Everybody makes a row
Down on Jollity Farm

All the little birds go tweet tweet tweet
The lambs all bleat
(Baaaah!)
And shake their feet
Everything's a perfect treat
Down on Jollity Farm

Regular is habit
The cocks begin to crow
(Cock-a-doodle-doo)
And the old buck rabbit
Sings stuff it up your jumper!
Vo doh dee oh

All the little ducks go quack quack quack
The cows all moo
The bull does, too
Everyone says how do you do?
Down on Jollity Farm
