For the first time, the Mary Martin
" is presented as a stand-alone two-hour special on NBC
instead of as part of an anthology series. This version, rather than being presented live, is shown on videotape, enabling NBC
to repeat it as often as they wish without having to restage it. Although nearly all of the adult actors repeat their original Broadway
roles, all of the original children have, ironically, outgrown their roles and are replaced by new actors.
