We're not astrology experts, but it sure seems like the moon is in the seventh house and Jupiter is aligned with Mars these days. That's because Hair, the exuberant hippie tribal love-rock musical is returning to Broadway. Even if you've never seen Hair (and missed this production's earlier incarnation at the Delacorte Theatre in Central Park last summer), there's a good chance you know the hit numbers from the show, such as "Aquarius," "Easy to Be Hard," Good Morning Starshine" and "Let the Sun Shine In." Broadway performances of the peace-loving show start on March 6 at the Al Hirschfeld Theatre, but we got an exclusive sneak peek as Gavin Creel, Caissie Levy, Will Swenson and the rest of the tribe let their hair down in rehearsal at the otherwise unoccupied Union Square Theatre. Check out how love is steering the stars of Hair!
