Toby Keith and more than 60,000 of his supporters gathered together Saturday (July 6) in Norman, Okla., to raise money for tornado relief efforts near Oklahoma City. Garth Brooks, Trisha Yearwood, Ronnie Dunn, Willie Nelson, Mel Tillis, John Anderson, Wade Hayes and Sammy Hagar also performed during the concert at the Gaylord Family -- Oklahoma Memorial Stadium on the University of Oklahoma campus. Carrie Underwood appeared via satellite from the Grand Ole Opry in Nashville to sing "Jesus, Take the Wheel" and "See You Again." Net proceeds benefited the United Way of Central Oklahoma's May Tornadoes Relief Fund in the aftermath of a May 20 twister that killed 24 people and destroyed homes, businesses and schools in Keith's hometown of Moore. His daughter, Krystal Keith, sang the national anthem to open the show that set a record for the largest paid audience for a concert at the stadium, exceeding attendance for the Rolling Stones and U2. The amount of money raised from Keith's Oklahoma Twister Relief Concert is still being tabulated. Donations are still being accepted on the United Way of Central Oklahoma's website.
