Wynonna will sign autographs on her tour bus at the Wal-Mart in Hendersonville, Tenn., on Monday (Dec. 13). Proceeds benefit Christmas for Kids, which gives 300 children spending money at Wal-Mart. In addition, she will perform in the round with Michael McDonald and Trent Willmon, among others, in Leiper's Fork, Tenn., on Dec. 18. The concert will raise money for the wife and four young children of Jack Ralls, a longtime area resident who was killed during a hunting trip. Naomi Judd will host the event.
