Concert highlights KC rallyBy PETE GRATHOFF and BOB LUDERThe Kansas City StarIan Byrne of the Elders struck the right chord with Wizards fans.“We're going to beat D.C. United,” the group's lead singer proclaimed to a crowd of about 300 on Saturday, “and all their underage kids. They should just stay home with their moms.”That was an obvious reference to D.C.'s Freddy Adu, the heavily hyped 15-year-old, who came on as a second-half substitute.The Elders performed in the Arrowhead Stadium parking lot before the game as part of a Heart of America Soccer Foundation rally.
