Cook sings National Anthem at Chiefs game

David Cook sang "The Star-Spangled Banner" at the Kansas City Chiefs' home opener this afternoon with his younger brother, Andrew, at Arrowhead Stadium in Kansas City, Mo. In a press release that went out in August, Chiefs President Carl Peterson said of the news:

"We are very excited to have David and Andrew perform the anthem for our first regular season game of the 2008 season."

Although the performance was not nationally-televised, it would not be a total surprise for video to pop up somewhere judging from all the Word Nerds out there.
