Watch Darren Criss Revisit the Clever, Self-Penned Harry Potter Musical That Made Him Famous on YouTube


Once upon a time, Darren Criss helped write A Very Potter Musical, a fan-made musical version of the blockbuster books that played at the University of Michigan in 2009. After the video surged on YouTube, Glee came calling, and the rest is history ... until this past month, when Criss flew into Chicago to rekindle the old magic at LeakyCon 2012, a convention for Harry Potter super-fans.
