When setting out on a British tour, what better subject to tackle than Britishness? Government ministers, religious leaders, educationalists - all of them have earnestly pondered what it means to be British. Now it’s the turn of stand-up comedians. What are our national obsessions? Who are our heroes? How can we be so nostalgic when we don't know any history? And why are we so good at getting drunk?

In their new show, Punt and Dennis set out to vaguely skirt round many of these questions. Along with many others, including the future of the BBC, whether alternative therapy ever works, whether schoolkids have any fun any more, and whether any of the towns visited on the tour don't have a Tesco.
