Hank Williams Jr. says there’s some serious history in Martina McBride’s Nashville backyard. Williams has always been a big history buff, and Martina McBride’s backyard isn’t the only one he’s searched. The singer says he often asks fellow artists if he can come over and scout around in their yards. He says McBride’s property is one of the more impressive because it’s part of the site of an 1864 battlefield. Williams will join a lineup of fellow artists to pay tribute to country legend Kris Kristofferson on March 16 in Nashville. The show will be taped for a television special.
