These are the two specially extended editions featuring all the bits you didn't hear on transmission! If you've ever wondered what it's like to attend a live recording of "I'm Sorry I Haven'ta Clue", the antidote to panel games, now is your chance to discover how much fun they are! These two extended editions of the programme, from 1995 and 1996, offer an exclusive glimpse behind the scenes, in the company of players Graeme Garden, Barry Cryer, Tim Brooke-Taylor, Willie Rushton and Jeremy Hardy. Hear Humph and the team setting up before and after a recording, catch the jokes intended only for the theatre audiences (including the naughty bits!), listen to Barry and Graeme as 'Alec & Denzil', early ancestors of their much-loved Hamish & Dougal creations, and thrill to Jeremy Hardy's first ever attempt at singing on the programme..."Clue" producer Jon Naismith introduces each programme, with additional material provided by Mrs. Trellis of North Wales. Warning: Contains some swearing.
