In a specially recorded edition of Start the Week Andrew Marr is at the Charleston Festival with Grayson Perry, Virginia Nicholson, Faramerz Dabhoiwala and Janice Galloway. As the home of Vanessa Bell, Virginia Nicholson's grandmother, Charleston was a by-word for sexual freedom and the Bohemian lifestyle. But Dabhoiwala insists that far from the 1920s being the time of real sexual revolution, that honour goes to the 18th century, the origin of our modern attitudes to sex. Janice Galloway brings the story up-to-date as she relives her adolescence in small town Scotland in the 1970s. And the celebrated potter Grayson Perry explores changing social attitudes in relation to taste: the choices people make in the things they buy and wear, and uses these details of modern life to create six tapestries, called 'The Vanity of Small Differences'.
