NORMAN, Okla. (AP) — Thousands of people have turned out in Norman for a concert benefiting Oklahoma tornado victims. Oklahoma natives Toby Keith and Garth Brooks are part of the star-studded lineup Saturday at the Oklahoma Twister Relief Concert at the University of Oklahoma's Gaylord Family-Oklahoma Memorial Stadium. The Tulsa World says the event was sold out, with officials estimating a crowd of nearly 65,000. The money raised from ticket sales benefits the United Way of Central Oklahoma. That organization has established a fund to aid victims of the tornadoes and violent storms that pummeled the state in May and killed dozens of people. A separate benefit concert last month hosted by Oklahoma native country music star Blake Shelton raised more than $6 million in donations and pledges.
