I assume this was a music hall song but I learned it at my mother's knee - well it was her 'party piece'

Raferty's pig was a wonderful animal
Built like a battleship sturdy and stout
His impudence would have disgraced any canibal
Ignorance written all over his snout
The night he broke lose there was such a calamaty
Women a screaming the men turning pale
Running and bumping coliding and jumping
And evryone making a grab for his tail

I know a few more verses but I would dearly like some hints on where I can learn the rest.
Thanks Mike
