Joe Chaikin, who founded the influential Open Theater in the 1960s, has written three other plays with Sam Shepard in addition to When the World was Green (A Chef's Fable): Tongues, Savage/Love and The War in Heaven: an Angel's monologue. The latter was first conceived when the pair spent four weeks teaching and working at the Loeb Drama Center in 1984. Their correspondence from 1972-1984, which stands as an eloquent commentary on an important decade of American drama, is published by New American Library.
