Both Betsy Palmer and Liza Minnelli wore their first-act Broadway costumes during their appearances on this telecast. Betsy, wearing a military uniform, had a dress rehearsal of ''South Pacific'' immediately following the telecast. Liza, wearing period young girl's day wear, including a sailor-type middy blouse, had to make the curtain for ''Flora, the Red Menace,'' right after ''I've Got a Secret'' ended.
