Everything else everyone else has said except Starship is no longer recent- Holy Musical B@tman is the most recent. Also, AVP3D/A Very Potter Senior Year has also been recently performed at Leakycon and will hopefully be posted on Youtube soon.
Jaime: Have you seen Holy Musical B@tman?
Lauren: No. Is it a Starkid play?
Jaime: Ya! It's based off of Batman and it's really funny.
