I'll go with Amazing Grace. I saw it in Chicago and loved it. I didn't find it religious or preachy. Just a story of a man who found the error of his ways (slave trader) and his redemption. Then he wrote Amazing Grace which the cast sang at the end of the show. Might not be a story for all but I enjoyed it. Also the cast and music were great. Planning my own NYC trip in Sept to ssee the show on Broadway!
