A funny thing happened when Billy Currington visited the David Letterman Show this week...David Letterman fell in love with "People are Crazy." Perhaps you've heard about it...maybe you even saw it...but it doesn't hurt to watch it again or share it with friends who might have missed it. You can check out David's gushing discussion of the song, along with Billy's live performance of it, and enjoy the finest country music has to offer, at least according to David Letterman.
