It's been recorded by Pat Sky on one of his really old albums; I think he may have written it, too. We don't have the album ourselves; maybe someone else out there can dig up the lyrics to this one. My husband likes singing the pieces he remembers, such as:

"His name is Giovanni Montini,
He lives in the Vaticanini,
He's Catholic, he doesn't use soap
He's Giovanni Montini, the Pope."

I'd love to get the words to the whole thing, too.
