Is it possible you're looking for the song "The Great Historical Bum"? ( - may also go by other names too)

It starts out - "I was born about ten thousand years ago

And there's nothing in the world that I don't know

I saw Peter, Paul and Moses playing Ring Aroud the Roses

And I'll whup the guy that says it isn't so."

If this sounds like it, I'll delve around for the rest of the words to post ... if not, I won't!
