I saw Eric Bogle do this once with his band (in Orillia, Ontario) and it was hilarious! Anybody got the lyrics? It doesn't seem to be in the Digitrad.
I'd also like the lyrics to his song "He's Nobody's Moggy Now". It's even funnier than "Plastic Paddy".
Eric did a great show when he was in Orillia a few years ago. Anyone seen him lately?
