'Cheap Tatty Review' was filmed as introduction to the first episode of 'Not The Nine O'Clock News', the show that was supposed to begin the week after the penultimate episode of 'Fawlty Towers'. However 'Not The Nine O'Clock News' was postponed until later in 1979 due to the imminent General Election. The sketch was aired when the final episode of 'Fawlty Towers' was shown during the first series of 'Not The Nine O'Clock News'. (thetvdb.com)
