The astonishing adaptation, by Malcolm McKay, of Max Arthur's bestselling and acclaimed book, "Forgotten Voices", is based on the spoken testimony of veterans of the First World War, collected by the Sound Archive of the Imperial War Museum in 1970. Five ordinary survivors - four men and one woman - movingly reveal their memories, which make up a complete narrative of an awesome war. "Forgotten Voices" will run at the Assembly Theatre, Edinburgh throughout August, before transferring to the Riverside, London.
