Country singer Keith Urban gave just a few hours' notice before performing a free concert Friday night in the parking lot of a large convenience store and gas station in north Alabama. Hundreds of people turned out for the show in Athens, about 100 miles (161 kilometers) south of Nashville. It was outside a Buc-ee's, a chain of roadside stores known for barbecue. “I came down to this Buc-ee's about a month ago. And when I left, I went, ‘It’d be kind of fun to do a show there,'” Urban told the crowd during the concert. Urban said his “cave man brain” told him it would be fun to set up a little stage for a small audience. “I swear to you, I thought maybe 100, 200 people,” Urban said as the camera showed a larger crowd. People started gathering hours before the show, news outlets reported.
