If you're a fan of The New Statesman you might just about make out the shadowy figure making his way down the steps of the Tube station. It's Rik Mayall or rather Alan B'Stard
Jon said "In one episode he has a secret meeting in an abandoned Tube station.
Rather than setting it in an existing station, the show invented the
fictional station of Haggerston and built a set. There's quite a
surprising level of attention to detail."
Jon's right, there is a good level of attention to detail. They've put up some old London Underground posters on the walls - I can just about make out one by Fougasse from the 1930's on the far right. In fact the whole look of the "abandoned Tube" definitely has a feel of the London Underground stations of the 1930s designed by Charles Holden.
I went to the fount of all knowledge on London Underground stations in film and TV - Nick Cooper's website and discovered that the episode was originally aired in October 1987 and is called "Waste Not, Want Not".
