Monty Python: And Now for Something Rather Similar

Actor Mark Bonnar is on a mission to understand more about the Scottish new towns in which he grew up, exploring the street sculpture made by artists such as his dad in the 60s, 70s and 80s. He discovers why the new towns are there and how they enticed people out of the bigger cities, and uncovers the surprising ways in which public art changed the new towns and the new towns changed public art. Mark's father, Stan, made sculptures that stand to this day on the streets of Glenrothes, East Kilbride and the Scottish new town that never was, Stonehouse. These new towns employed town artists to make artworks in the very housing precincts the new residents were moving into.
