It is not--nor was it ever-- a Richard v. Karen scenario.
For myself, anyway, it is about History of "the Carpenters" as a duo.
If there is "source" material/documentation that differs from one another,
I take the earliest known source as closest to the truth--whatever that "truth" entails.
Sources further from the event are less reliable--that is generally accepted when digging for historical evidence.
Nothing else to it.
Just saw a new and much longer promo for the ABC show Big Sky, coming in November 2020. They play much more of Top Of The World throughout the promo. Some of it very clear, and some partially muted, that it’s a mystery, thriller type show. Looks interesting. Hope they actually use it in the series when it aires next month.
