Before Herman Cain was a Republican presidential candidate, he was the president and CEO of Godfather's Pizza.

Someone tracked down a video of Cain at an event in Omaha, Nebraska, 20 years ago singing about pizza to the tune of the John Lennon song "Imagine."

It's kind of embarrassing, since it's such an iconic song, and the lyrics are about things like "mozzarella" and "anchovies on the side." He even steals a line from Orlando's in Lubbock when he says, "Give pizza chance!"

He's actually a pretty good singer though.
