The announcement was made in conjunction with the cast's appearance on the July 13 episode of The Tonight Show with Conan O'Brien. Hair won the 2009 Tony Award for Best Revival of a Musical.
In a statement, Oskar Eustis, artistic director of The Public Theater and one off the show's producer said: "The Public Theater has always aspired to make theater that matters, that speaks to the great social issues of our time. Hair has never been just a show; its message of change and hope and inclusion is one we try to live, not just preach. This is the moment when we need to recognize the right of all citizens, gay and straight, to have their love and their unions acknowledged by the state."
