Although nothing is definite, there's a strong possibility that Tim McGraw will join Hank Williams Jr. and Charlie Daniels on tour next year. The three superstars apparently hung out on Tim's farm in Leiper's Fork, Tenn. earlier this week - the same farm that was once owned by Hank,Jr. Tour details are sketchy, but Tim's manager says, "We are intrigued by the whole concept. It could be cool."
