We all love an embarrassing #tbt social media post – but for one night only, put down your smartphone, close out your Instagram, and ignore your Twitter feed, because New York’s 54 Below has the greatest real-life Throwback Thursday celebration in town. #tbtLIVE features a cast of stage stars reprising old performances from the days when they were just Broadway babies – whether it was a summer camp solo or a college chorus line. More than a dozen theater stars, including Alex Finke (Anything Goes), Grey Henson (The Book of Mormon) and Adam Kaplan Newsies) will come to the stage armed with yesteryear’s photos and videos, ready to relive the kind of adolescent stage performances only a mothers could love.
