Karl & Warwick Interview

Does anybody know where I could find the video of an interview for Idiot Abroad 3 where Karl is trying to argue with Warwick that David Bowie wouldn't go on about being in Labyrinth every conversation 20 years later like Warwick does with Star Wars and say nobody was looking at Warwick because he's famous when they were travelling, nobody would recognise him because he's always dressed up as some sort of goblin at which point Warwick points out he was in Labyrinth too?
