After sociologist Dr Gerda Reith, of Glasgow University, discusses why gambling is such a cultural flashpoint, presenter Laurie Taylor welcomes James Sharpe, Professor of History at the University of York and author of a new book, Remember, Remember the Fifth of November (Profile Books Ltd), to analyse Britain's celebration of Bonfire Night and how it has changed over the centuries.
