Tim McGraw and Faith Hill will bring back the Soul2Soul tour this summer, according to Billboard. However, no cities have yet been announced. The couple expects to return to the road in June, July and August. Last year's Soul2Soul II tour grossed $88.8 million, making it the fifth-highest grossing tour of 2006. McGraw will release a new album, Let It Go, which features the "Last Dollar (Fly Away)" and two duets with Hill, on March 27.
