The event was held to mark the Tony-winning musical’s first anniversary on Broadway.
Dear Evan Hansen celebrated its first year on Broadway on December 10.
The production said thank you to its "Fansens" with a free "Fan Appreciation Day" performance at which the Music Box Theatre was filled with fans awarded tickets through a digital lottery. Leading up to the performance, the Drama Book Shop hosted a signing where book writer Steven Levenson and director Michael Greif greeted fans eager for autographs.
With a Tony-winning score by Benj Pasek and Justin Paul, and a Tony-winning book by Levenson, Dear Evan Hansen is described as follows: "All his life Evan Hansen has felt invisible. To his peers, to the girl he loves, sometimes even to his own mother. But that was before he wrote the letter — that led to the incident — that started the lie — that ignited a movement – that inspired a community — and changed Evan's status from the ultimate outsider into the somebody everyone wants to know. But how long can Evan keep his secret? And at what price?"
