Looking for a good time? Hurry and grab your tickets for tonight’s debut of Hair on Broadway. What began as a celebration of the show’s 40th anniversary with performances in last year’s Shakespeare in the Park has transformed into a full-fledged rock tribal musical. Director Diane Paulus says of her new show: “I really feel like as a director, you look for these moments when something you do in the theatre actually hooks up with the larger culture.” The free-wheeling ‘60s and ‘70s are chronicled through bombastic hits like “The Age of Aquarius” sung by a huge, young ensemble cast. Gavin Creel, one of the leads in the show, recently spoke out about marriage equality and gay rights.
