"I'm gonna walk out there and follow my heart and follow the vibe of the room," Bryan told reporters during a Thursday morning press conference.

"I may get out there and go, 'I'm about to pass out, I need to get this thing over quick,' or I may get out here and feel really good in the moment and try to milk it a little bit," he teased.

Bryan later dedicated his performance to service men and women around the world, saying that performing the anthem is his way of honoring their service.

"I never had the opportunity to serve in the military, but I feel like a little way I can serve my country is using my voice to do the anthem and always uplift and bring some smiles to men and women in the armed forces," he said.
