Kenny Chesney had a birthday to remember on Monday (26MAR07) night when pals Tim Mcgraw, Faith Hill, Jewel and Gretchen Wilson turned a low-key Nashville, Tennessee party into a star-studded affair. The country star booked out venue the Tin Roof and planned to perform there for fans, family and friends. But the evening quickly became a superstar jam session when Wilson, Montgomery Gentry, KIX BROOKS, BIG + RICH, SARA EVANS and TRACY LAWRENCE joined his band onstage, while other celebrities watched from the crowded club floor. Chesney, 39, performed a set of hits and covers, including renditions of Lynyrd Skynyrd's GIMME THREE STEPS and U2's WITH OR WITHOUT YOU.
