Imagine standing on a stage singing, dancing and talking for 40 hours and eight minutes. That is exactly what the Midnight Swinger did on April 29 and 30 as he broke the Guinness World Record for the longest stand-up comedy show by an individual. David Scott a.k.a. The Midnight Swinger is more of an entertainer than he is a comedian. His shows include singing, dancing and costume changes that leave the crowd mesmerized. “Damn, I look good,” he's prone to boasting. He performs tonight at 7:30 at the Improv and has shows scheduled through Sunday. Tickets are $17 to $20. (Hammond)
