Letter : Protesters knew Augustus well

Sir: David Sweetman ends his review of the new edition of Michael Holroyd's biography of Augustus John ("Avant-garde sex life of an old- fashioned artist", 31 August) with the statement that when he joined the Committee of 100 sit-down in Trafalgar Square in September 1961, "his era was by then so long gone that no one amongst the young demonstrators had any idea who he was".

What nonsense! Neither was he so old nor were we so young that we didn't know perfectly well that one of the greatest living artists had joined us in the campaign against nuclear weapons.
