Lynyrd Skynyrd and Hank Williams Jr. have announced a series of concert dates for 2008, following up their successful Rowdy Frynds tour together last year. The 20-city tour begins April 4 in Hershey, Pa., and concludes June 14 in Jacksonville, Fla. Last year, the collaboration grossed more than $10.5 million. "Our following of fans fits together perfectly," said Lynyrd Skynyrd vocalist Johnny Van Zant. Williams added, "Last year was incredible. How could we not get together for another round?"
