I'm trying to find the lyrics to a song called O'Rafferty's Pig, as a surprise for a friend who just turned fifty. All I know about it is that it has been sung by a Steve Benbow in 1960, by Gorden Lightfoot (though not recorded) at a concert or live performance, and that it must be quite old as it was sung to my friend as a boy by his mother. I also have some of the lyrics:

Well O'Rafferty's Pig was a wonderful animal
Built like a Battleship solid and stout
His ignorance would have disgraced any cannibal
Impudence written all over his snout
The night he broke loose there was such a commotion
Wi' women all screaming and men turning pale
Running and jumping colliding and bumping
The night that O'Rafferty's Pig ran away

If someone could help me that would be great :)!

Thank you,
