Eve Pumb is wearing the same dress that Maureen McCormick wore in the Brady Bunch episode "Brace Yourself," Season 1, Episode 20, when she went to the school dance.
One of the patrons in the audience during Donny Osmond's performance was Carolyn McNichol, the mother of Kristy McNichol and James (Jimmy) McNichol. In 1977, Kristy made a guest appearance on "Donny & Marie" (variety version). Donny would return the favor by appearing on a Kristy & Jimmy McNichol ABC TV special promoting the brother and sister RCA 1978 self titled album.
