Country singer Keith Urban gave just a few hours’ notice before performing a free concert in the parking lot of a convenience store and gas station in north Alabama. Local police say about 5,500 people turned out for the show Friday night in Athens, about 100 miles south of Nashville. It was outside a Buc-ee’s, a chain of roadside stores known for barbecue. Urban says he was at the store about a month ago and thought it would be fun to do a show there. A video showed Urban working behind the store's food counter, pouring barbecue sauce on brisket.
