The original show remained virtually unchanged from 1971 until October 1993. Additional Audio-Animatronic figures of Gerald R. Ford, Jimmy Carter, Ronald Reagan, and George H. W. Bush were then added when each entered into office. Lawrence Dobkin continued to be the narrator, and re-recorded the roll-call for each new addition. The only major feature that changed before 1993 was the original adaptation of "The Battle Hymn of the Republic" that served as part of the finale of the show. It was the same adaptation used in Great Moments with Mr. Lincoln. The adaptation was done in a lower key, and instead changed for a revised adaptation in a higher key.
