The Professional Bull Riders' legendary cowboy entertainer (rodeo clown to the uninitiated) Flint Rasmussen kicked off Saturday night's events at the PBR World Championships by leading the crowd of 20,000 rodeo fans in an emotional a cappella rendition of the American national anthem.

Rasmussen, stepped on stage at the packed T-Mobile Arena in Las Vegas and opened the event by announcing, "At this moment of the show, we usually introduce an anthem singer to perform our national anthem," he said, adding, "But, tonight I am honored to stand before you, the greatest fans in the world, as we together, as one giant choir of 20,000 people, perform the greatest song that's ever been written."
