Series 4's episodes were cut down to 10 minutes, instead of 15. This is the least-remembered series of all. It is the hardest to obtain copies of. This series was repeated on Mondays and Tuesdays, with an occasional gap of one week, from March to June 1996, commencing the week following the end of the original transmission of series 6. The opening titles to this series and the remaining series were edited short, so that by this point, the full verse of the theme song is not heard in both opening and closing titles (instead concentrating on one verse each). The opening titles now only contain clips from episodes in the series, with no material specially shot for the opening titles. The practice of having clips from earlier in the episode of actors appearing in character over their credits in the closing credits sequence was gone, with random clips from the episode appearing in chronological order throughout the closing credits sequence. This would remain the normal fashion of episode credits for the series until the end (with a surrounding graphics change for series 9).
