Andrew Graham-Dixon presents the latest edition of The Culture Show from Glasgow and gets a sneak preview of the National Galleries' forthcoming exhibition of paintings by 16th-century Flemish artist Jan Gossaert. Andrew reclaims this modern master from relative obscurity and argues that the work on display changed the course of Northern Art, paving the way for later giants such as Peter Paul Ruebens. In slightly more contemporary happenings: Guy Walters investigates the extreme side of online behaviour, Maxine Peake and Anne-Marie Duff discuss their roles in the latest stage versions of two Terence Rattigan plays, and Miranda Sawyer meets the members of alt rock band Elbow to talk about their latest album.
