Chart-topping crooner Josh Groban, who has always sported a delicious mop of curls, checked out the shining, gleaming, streaming, flaxen, waxen peaceniks at the Tony-winning revival of Hair on Broadway. After grooving to the performance at the Al Hirschfeld Theatre on January 22, Groban hopped on stage to pose for pics with the fun-loving hippies. The Tribe even adorned the singer-songwriter in some far-out love beads. Check it out… and peace!
