In June 1976 a two-hour special was produced to celebrate the 1000th episode of Number 96. Entitled And They Said it Wouldn't Last, the special was presented by former stars of the show from the show's actual sets and remains probably the best overall resource of the series short of screening the actual episodes. Indeed the special contains much footage from the early black and white period of the show that no longer exists in any other form; after the full changeover of Australian television to colour production and broadcasting by Easter 1975, no one ever dreamed viewers would watch black and white television again, and few of the black and white episodes were saved. All episodes from the first few weeks - episodes 1 to 15 - remain, and episodes 31 to 35 were also kept. Unfortunately the rest of the 1972 episodes, all of the 1973 episodes, and all but one of the black and white episodes from 1974 - about two thirds of that year's episodes - are lost. Just one black and white 1974 episode, episode 450 from the opening week of that season, survived the purge. All of the episodes produced in full colour - starting with episode 585 first broadcast in August 1974 through until episode 1218 - remain. It is some consolation that highlight clips from a few of the lost episodes were saved as small clips in And They Said it Wouldn't Last.
