Alan Jackson celebrated crossing the 50-million album sales milestone by chowing down on grits and bologna sandwiches. People magazine reports Jackson, his family and about 400 friends, including Trace Adkins and Mel Tillis, gathered in Nashville Wednesday night to honor Jackson. The down-home grub was a nod to Jackson's song "I Still Like Bologna," on his latest album "Good Time." Jackson can't believe his longevity. He says back when he released his first album in 1990, he was just glad to have a record deal. He says, "I figured if you could last five years you were lucky, so that was the only goal I could see. This would have been unbelievable."
