'Live on Letterman' Webcast

Jason Aldean should start counting down the days to October 16, when the singer’s next album, ‘Night Train,’ will be ready for the purchasing. Unfortunately, that’s still a few months away. But the good news is, fans of the ‘Fly Over States’ hitmaker can get a sneak peek of his new tunes when he takes them to the internet through David Letterman’s ‘Live on Letterman’ webcast.
