This last slightly longer Rediffusion episode, broadcast later in the year, was an intriguing mixture of new material and newly shot reprises of sketches from the series. It includes slicker new versions of the ‘Travelling Kettle’ sketch and the ‘Stool Pigeon’ sketch (with Palin’s undercover copper now whistling the theme from BBC police procedural Dixon of Dock Green to add a subtle extra gag), latterly disturbed by a little off-screen set disruption. Meanwhile, The Bonzos are finally able to perform ‘I’m the Urban Spaceman’, with perhaps the most elaborate prop they ever got for the show: a Gerry Anderson–style spacecraft that actually moves, while a grandly orchestrated pre-recorded coda to the song plays elegiac accompaniment.
