That too was one of my favorite aspects of the production. Broadway musicals have grown increasingly slick and packaged for worldwide consumption. Billy Elliot, though clearly a juggernaut on the international stage and with the clout of Universal behind it, still feels personal and handmade.
Begin at the beginning and go on till you come to the end: then stop.
