Free Thinking - Feminism in Theatre

American novelist Jonathan Lethem discusses the singer Pete Seeger, whose death has been announced today. Martin Creed's artworks have included a room full of balloons and a room containing only a light switch. Matthew Sweet considers how Creed questions what are the limits to art, talking to Creed himself, art critic Charlotte Mullins and comedian Waen Shepherd. And, as their latest plays open on the London stage, Free Thinking brings together the director and writer Carrie Cracknell and the writer Abi Morgan to consider feminism in theatre.
