8/6/2007 Stephen L. Betts Clay Walker will make his first appearance on NBC's late-night talk show Last Call with Carson Daly on Friday (Aug. 10). "This is going to be fun," says and excited Clay. "Carson and I play golf at Pebble Beach every year, so this is going to be like two friends hanging out instead of it being like work. Tune in, you never know what might happen!"
