David Tennant hosts (again, as this is a repeat, the BBC's version of a time machine) a special edition of the quiz show with team captains Phill Jupitus and Noel Fielding. The guests are actor Bernard Cribbins, who starred as Wilf Mott in the episodes that saw the 10th Doctor regenerate into Matt Smith, actress and former companion of the Time Lord Catherine Tate, plus platinum-selling jazz artist Jamie Cullum and Radio 1 DJ Jo Whiley.
