I watched this on PBS the other night. It was excellent.
The two act, four character play is a conversation between Thoreau and Emerson set during the final two days Thoreau spent in his cabin before leaving Walden Pond. Simple and fun to produce, over 7,400 colleges, schools, community theaters and homeschools have registered performances of the Walden play in 39 countries. The Walden play script is available in English, French and Spanish.
