Allen,

You beat me to it. The lyrics are on this thread attributed to William Maginn. I was under the impression (based on the sleeve notes from the Prosperous album) that Christy had written the words himself. He certainly claims to have set the lyrics to the tune of "The night before Larry was stretched". I don't know what the album credits have to say about authorship.

This is about the only song that I do around Paddy's Day that I don't normally sing at other times of the year.
