To mark the 100th anniversary of the Scouting movement, a celebrated roll call of former Guides, Scouts, Cubs and Brownies - including Cherie Blair, Ronnie Corbett, Betty Boothroyd and Arthur Smith - relive nights under canvas, fiddling with knots and singing around the campfire. Meanwhile, Neil Morrissey mucks in with some of today's Scouts for a weekend at camp. Plus, historical and classic comedy clips from the likes of Harry Enfield, the Goodies and Little Britain.
