Gareth Malone and Karen Gibson conclude their special series exploring how the season has been celebrated in Britain across the centuries. They discover why a ban on Christmas led to rioting in the streets, and how the festivities were revived with a vengeance in Victorian times. As they trace the stories behind now-common traditions – and take part in less familiar ones such as pub carolling - the archbishop of Canterbury explains how he celebrates Christmas, and why its meaning remains so relevant today. Plus, with their shared passion for music, Gareth and Karen orchestrate a rousing musical finale, putting a twist on a familiar favourite to celebrate the season. Show less
