Gotta love those Jersey Boys! A live appearance by the quartet—no matter who’s playing what—never fails to astound. Having said that, judging from the performance of the Las Vegas stars of the show last night on NBC’s America’s Got Talent, Sin City’s got a rock-solid group of boys. A special shout-out to Rick Faugno, one of Broadway’s top hoofers over the past decade in shows like Wonderful Town and Chitty Chitty Bang Bang, who’s now proving he’s a leading man as Frankie Valli. Joining him are Erich Bergen as Bob Gaudio, Jeffery Leibow as Nick Massi and Deven May as Tommy DeVito. The medley got all three Talent judges on their feet. Watch the video below to find out why!
