A reunion tour many years in the making has finally materialized and comes to a theater near you. Cheech and Chong: Light Up America brings the duo back together for some modernized stoner humor. Will Cheech, who dumped his burned-out image to become a more "serious" actor, pick up where he left off? Will Chong draw on That 70's Show for inspiration? Find out Sunday night. 8 p.m., Carol Morsani Hall-Tampa Bay Performing Arts Center, downtown Tampa, $39.50 and $59.50, 813-229-7827.
