On the campaign trail with Felicia Sonmez

GOP presidential candidate Jon Huntsman showed off his musical prowess on the “Late Show with David Letterman Wednesday night.

At Letterman’s urging, Huntsman, who played in a high school band called “Wizard,” borrowed bandleader Paul Schaffer’s keyboard and rocked out to the classic Chuck Berry song “Johnny B. Goode,” with Shaffer on vocals.

Huntsman isn’t the first presidential candidate to show of his musical skills on television. Bill Clinton famously played his saxophone on Arsenio Hall’s talk show in 1992.

Nor is Huntsman the first 2012 GOP candidate to appear on Letterman. Mitt Romney read a Top Ten list for Letterman earlier this week.
