VIDEO: Andrew Keenan-Bolger Performs at BE MORE CHILL's Post-Show Hang

We're getting an upgrade thanks to Andrew Keenan-Bolger's performance at Be More Chill's final post-show hang! Check out the video to see the Broadway favorite sing 'Blue Hair' alongside the show's Tony-nominated composer Joe Iconis!

The show's previous 'hangs' include Alice Ripley, Gaten Matarazzo, Taylor Trensch, George Salazar, Alysha Umphress, and Lauren Pritchard.

What if popularity came in a pill? Would you take it, no questions asked? In Be More Chill, achieving that elusive "perfect life" is now possible thanks to some mysterious new technology-but it comes at a cost that's not as easy to swallow. What could possibly go wrong? Blending the contemporary with retro sci-fi, this thrillingly exciting, comically subversive, and deeply felt new musical takes on the competing voices in all of our heads. And ultimately proves, there's never been a better time in history to be yourself-especially if you're a loser...geek...or whatever.
