'Late Show With David Letterman': Jon Huntsman Rocks Out With Paul Shaffer And The Band (VIDEO)

GOP Presidential candidate Jon Huntsman's secret past as a wannabe rock legend was revealed to the world on "Late Show" (Weeknights, 11:35 p.m. EST on CBS). David Letterman had what he called a "rather incriminating photo" of Huntsman and his old high school band, Wizard.

"I thought I could make it big," Huntsman laughed. "I wanted to be Paul Shaffer."

So Letterman offered him the next best thing, urging Huntsman to head over and join the "Late Show" band for a quick number. With Huntsman on keyboard, they played a bit of Chuck Berry's "Johnny B. Goode," which mirrored Bill Clinton's saxophone moment on "The Arsenio Hall Show" during his first campaign.

"Late Show with David Letterman" airs weeknights at 11:35 p.m. EST on CBS.
