Heard one which went as follows:-

Oh the carrion crow he sat upon the oak
With a ring dong dilly dong kyro dee
Watching the tailor mending his cloak
With a ring dong dilly dong kyro dee,
Hi fa-lee, fa-lee, fa-lero,
Hi fa-lero lero lee,
And it's up jumps Tom, Ringing of his bell
With a ring dong dilly dong kyro dee!

(All the nonsense words repeat in each verse, the meat of it goes thus)

Oh wife bring me my old bent bow
That I may shoot at the carrion crow

The tailor shot but he missed his mark
And he shot his old sow straight through the heart

Oh wife bring brandy in a spoon
For our old sow is in a swoon

When the old sow died all the bells did toll
And the little pigs wept for their mammy's soul

Kids love it, but if you can get a good adult audience to sing harmony it sounds great.
