Before he went on stage, he saw a tweet from a listener who was excited because it was her last day in Nashville, she was touring the Opry and found out he was performing at the show that night. She purchased tickets and said it would be her first time seeing a show there.
During his set, Bones found her in the crowd and brought her up on stage. He decided to impromptu have them do a duet together of "You Are My Sunshine" as a funny thing. Turns out, she really knows how to sing. So Bones told her to sing the rest of the song and the crowd went crazy.
