In this series of The Essay, recorded in front of an audience at the Hay festival earlier this week, five writers take George Orwell's essay title Why I Write as a starting point for their own explorations. The writers include the screenwriter, novelist and author of the opening ceremony for the 2012 Olympics, Frank Cottrell Boyce; the editor and translator Daniel Hahn; Horatio Clare, whose first book was set on the hillsides where he grew up around Hay itself; and the Welsh poet laureate, Gillian Clarke. Part of Radio 3's week-long residency at the Hay Festival, with programmes CD Review, Lunchtime Concert, In Tune, Free Thinking, The Verb and World on 3 all broadcasting from the festival.
