Thomas Rhett Jason Aldean Night Train tour

Chris McKay, Getty Images Jason Aldean headlined the first-ever concert at the University of Georgia's Sanford Stadium in Athens, Ga., with more than 60,000 fans packing the outdoor venue Saturday night (April 13). Early concertgoers tailgating in the parking lot were surprised when Jason himself joined in the party.
