DAYTONA BEACH - Chubby Checker twisted and shouted, Brooks & Dunn were "rockin' and twangin'," and Trisha Yearwood provided an elegant national anthem as six Air Force Thunderbirds roared above the luxury tower.
Celebrities set the scene for Sunday's 50th anniversary of the Daytona 500, a spectacle in itself with some 200,000 fans on hand. Yearwood, a Grammy Award-winning artist, said she never has performed in front of so many people, although she has sung at the World Series, NFL games and even the closing ceremonies at the Olympics.
"Nothing like this," she said. "I didn't even know the number until I got here. But it's such great energy. It's amazing."
Yearwood admits she doesn't have a favorite driver, although Tony Stewart and Kasey Kahne -- "when he was like 12" -- once set foot in her house.
"I drove the Tony Stewart simulator car this morning," she said. "But don't tell him I wrecked it."
Several fans were lucky enough to pose for photos with Yearwood in the Daytona infield after her national anthem.
