Fifteen years ago, the now major rock band The National was formed when five buddies from Cincinnati had transplanted themselves to Brooklyn.  That was 1999, and after a decade and a half of working their tails off in bars and on the road, The National are bona fide rock gods.  Their latest album Trouble Will Find Me is nominated for a Grammy Award for Best Alternative Album, and CBS This Morning‘s Anthony Mason sat down with three members of the group to talk about their rise to fame.
