The brief kiss between Nancy Sinatra and Sammy Davis Jr. was the first interracial kiss shown on network television. [The first interracial kiss often is attributed to Plato's Stepchildren (1968) (which aired 22 Nov 1968), where William Shatner, as Captain James T. Kirk, is compelled by aliens, who have "psionic powers", to kiss Lt. Uhuru (Nichelle Nichols).]
On the DVD commentary track, Nancy Sinatra spots Teri Garr as one of the dancers in the opening number but director Jack Haley Jr. had forgotten Garr was involved.
