Following 2009's conquest of Hadrian's Wall, Mark Radcliffe and Stuart Maconie embark on a bold new challenge - walking over 80 miles of the Jurassic Coastline. In the third live travelogue, Mark and Stuart are in Sidmouth, home to a week-long folk festival in summer. Their special guests are Squeeze who will perhaps, as befits their seaside location, be Pulling Mussels (From the Shell). They're also joined by the Nashville-residing singer-songwriter Caitlin Rose and Masterchef 2009 winner Mat Follas.
