BAGHDAD, Iraq -- More than 500 soldiers, sailors, Marines and airmen crowded around a stage at a U.S. installation to hear country star Toby Keith and 1970s rocker Ted Nugent. "You guys are doing a great job over here," Nugent told the audience Saturday. It was one of several stops in Iraq for the pair, who are visiting Iraq as part of a USO tour. They had previously performed for U.S. service members in Kosovo, Germany and Italy.
