The inspiration? Actress Diahn Williams. Her first major role was as one of the girls (Terry) in the single-season sitcom Harry’s Girls (1963-1964). The series, set in then-modern times, featured a small American vaudeville troupe that performed dance numbers in Europe (because acts like theirs had long since fallen out of favor in the United States).
Diahn continued to appear on various television shows until the mid-1970s, when she quit acting to become a lawyer.
In terms of spelling, do you prefer the unusual “Diahn” or the standard “Diane”?
