The Moment That Changed It All For Little Big Town

Four years ago this week, Little Big Town's "Pontoon" hit the top of Billboard country singles chart -- where it would stay for two weeks.  The song was a game-changer in many ways. It was the first number-one for the group, who had been putting out records since 2002. And it gave them the recognition that they deserved.   Jimi Westbrook says the song pushed their career into forward motion. The group won a Grammy for Best Country Duo/Group Performance in 2013 for the song.
