Tim McGraw will host his next Swampstock in 2008, following a decision to hold the charitable event every other year. In 2006, Swampstock became a part of Neighbor's Keeper Foundation, the charity co-founded by McGraw and wife Faith Hill. The event, which includes an outdoor concert, has drawn thousands of people each year to Rayville, La., near McGraw's childhood home. "It's a lot of work to put this event on each year, and I know it's asking a lot of the staff, the volunteers and, of course, the other artists and their bands," said McGraw. "I want to keep the event fresh and important in the eyes of the community -- and continue to grow Swampstock. Holding it every other year will help us to achieve those goals."
