Nobody guessed that a solo show from comedian and writer Alex Edelman would become a hit, but that’s what happened with Just for Us, which is now running through late July at the Greenwich House Theater. Originally, the piece, about a strange and uncomfortable excursion Edelman took one night to a meeting of white nationalists in Queens, “was meant to be just a sweet and small six-week thing.” Trust us, if you’re a New Yorker (or you’ve ever been a New Yorker), you’ll laugh—a lot. (Steve Martin, Jerry Seinfeld, Ben Stiller, Billy Crystal and Sarah Jessica Parker have all seen the show) “I like jokes and shows that are a little more ‘high-risk’ than the average standup thing,” Edelman says.
