Few episodes from the show's first two decades survive; although some shows were recorded to videotape for delayed broadcasts, the tapes were reused and eventually discarded. In 2012, a vintage tape was located on the Walter J. Brown Media Archives & Peabody Awards Collection Web site archive list by Rick Klein of The Museum of Classic Chicago Television, containing material from two 1971 episodes. WGN reacquired the tape and put together a new special entitled "Bozo's Circus: The Lost Tape," which aired in December 2012.
