Another childhood one from my native Falls Rd. area of Belfast was:

King Billy was a bendy soldier,
He fought for the bendy crooks,
He fought for the sake of Linfield*
To buy a pair of boots.

When baps and scones* were flyin',
He got hit by a hard barm-brack,*
And he dropped dead like a tatey bread*
All warapped in the Union Jack.

*Linfield - local Unionist soccer team;
*baps and scones - bread rolls;
*tatey bread - potato pancake

I'm surprised Alison or Jimmy C haven't weighed in with some more.
