Brett Young performs "Soldier" with Gavin DeGraw
Brett Young surprised country music fans everywhere when he brought out one of his biggest songwriting inspirations, Gavin DeGraw, to perform with him. Young explained to the crowd how Gavin made him want to get into songwriting in the first place, and said, "I've seen a lot of Gavin DeGraw shows, but tonight is the first time I get to share a stage with Mr. Gavin DeGraw." Then, after Gavin appeared on stage and sat down at a keyboard, he talked about his friendship with Brett, and asked the fans in the arena if there were any US Military members out there. Then, he told them, "Brett and I want to play this song for y'all and dedicate this song to the soldier in all of our lives."

Keith Urban had a special surprise for fans: Maren Morris. Keith performed a lot of new music from his new album Graffiti U, but he also included some songs from previous records like his Miranda Lambert collaboration "We Were Us" from Fuse. But instead of bringing out Miranda to sing her part, Urban invited Maren Morris (who was rocking a Texas football jersey) to perform with him, who performed her own set earlier in the night. Keith explained to the crowd, "We want to do something a little special tonight."
