There are multiple clues that this episode was, like the rest of the series, pre-recorded, despite the conceit that it was "live".
James starts the show by excusing rain drops on a camera that's been outside the studio, suggesting that it's probably dry where the viewers are. Then there's the instance of a guest from the "previous" week, Shush Shoo, coming back to the show.
Yet probably the most explicit is James asking for a shot from a hand-held camera, saying that "It doesn't matter about the wrong date, we haven't set it up properly" - the date displayed is 13/2/1995.
