Over the weekend, Thomas Rhett performed at the Celebration of Caring Gala, hosted by Peyton Manning, to raise funds for the Pediatric Intensive Care Unit at Peyton Manning Children's Hospital at St. Vincent. Rhett invited Manning on stage to cover his dads 1995 hit 'That Ain't My Truck', and it looked as though Manning is a pretty big fan of the song, because he didn't miss a word.
