This episode was suppose to coincide with Princess Diana's wedding in 1981.
Family Ties started in 1982, Twisted Sister We Are Not Gonna Take it was 1984, Bangle's Eternal Flame was in 1988. Worse NOONE called princess Di "people's princess" until Tony Blair siad it after her death. I lived through the 1980s HS/college so to me they tried pulling a fast one on me. If you do a show that takes place withen folks lifetime at least set each episode so everything falls withen same year.
