If anyone hasn't listened to "Dolly Parton's America" (https://www.wnycstudios.org/podcasts/dolly-partons-america), I highly recommend it.
Does a great job interviewing Dolly and discussing with her (and those two are around her) who she is, her life events, her thoughts on life. I knew people loved Dolly Parton before I listened but didn't really know why and the podcast helped me understand a bit more of it. It features a LOT of one-on-one time with Dolly in a way that I don't often find docu-series do. It's fantastic!
One minor fact about Dolly I've always found fascinating is that she was married to the same dude for almost 60 years, until he passed away recently. I mean, being as famous as she was as an entertainer - that just seems like an extreme anomaly.
Except for the part where they try to inject their woke agenda into it by trying to suggest Jolene is a lesbian song. Nothing wrong with LGBTQIA+ but that part was super cringe as it was clear they were inserting their own adgenda rather than just interviewing Dolly Parton
My favorite Dolly story that she sometimes tells in talk shows was when she heard about a Dolly Parton Look Alike contest and entered it. She came in second place.
