There were so many memorable moments during the festival, like The Band Perry performing a cover of “Uptown Funk,” Rascal Flatts involving fans in a “Life is a Highway” sing-along, everyone putting their phones on during Justin Moore's performance of "If Heaven Wasn't So Far Away," and Darius Rucker playing “Truth or Darius” and being dared to crowd surf across the audience.
