One of those being married is singer-actress Terri White, who will soon be seen in the Kennedy Center's Broadway revival of Follies. White will marry jewelry designer Donna Barnett. Two other couples will also exchange vows on the St. James Theatre stage: actor Ryan Dietz and playwright Josh Levine; and stage doorman John Raymond Barker and Jujamcyn Theaters usher Jared Pike.

The marriages will be performed by 2011 The Scottsboro Boys Tony nominee Colman Domingo, who has been ordained by the Universal Life Church for the ceremony.

The current Broadway engagement of Hair is a stop on the national tour of the Tony-winning revival, which launched in fall 2010. It re-opened on Broadway at the St. James Theatre July 13.

Cast members from the original 2008 Broadway revival of the musical also attended the National Equality March in Washington, D.C. in October 2009 to commemorate the anniversary of LGBT activists who first marched on Washington in October 1979 to fight for equal rights.

"Hair has always been more than just a show - its spirit of activism means changing the world, not just entertaining it," Public Theater artistic director Oskar Eustis said in a statement. "The entire company of this amazing production went to Washington to march for marriage equality, and we are honored to be back on Broadway helping New York show the world what real equality means." "The theater is the place where we come together to celebrate and affirm who we are," Jujamcyn Theaters president Jordan Roth added in a statement. "It is the place where we stand in front of our community to speak our truth. That is theater. And that is also a wedding. It feels so very right then at this moment of historic magnitude for all of us to host some of the first same-sex weddings in New York State at our theatre. Our home."
