Katie Couric unveiled one of her hidden talents on Monday's "Late Late Show With Craig Ferguson": she plays a mean harmonica.
Ferguson told her that there was no band, and so she would have to be played off the set to either a harmonica or to "awkward silence." She surprised him by saying she could play the harmonica, and proceeded to treat the audience to a rendition of "Shenandoah."
In the car ride after show, Couric treated her fellow passengers to a reprise of the song.
