This is the Dolly/Linda/EmmyLou doc I mentioned earlier in the thread:

It goes beyond a typical country biopic, as it looks at the similarities and differences of three completely different women born in different parts of the USA at the same time (D&L 1946/ EL 7)
The mutual respect is palpable, as is the decades long friendship, particularly between Linda Ronstadt and EmmyLou Harris, who were friends long before they met Dolly.
It’s also tinged with sadness, as Linda doesn’t film the studio parts with the others, due to the degenerative brain disease that ended her singing career.
Funnily enough, both L and EL had negative opinions on Dolly’s appearance in the early days (being cool, ‘hippy’ types themselves). I haven’t watched this in a while but If I recall correctly, they point out that Dolly is far more talented than either of them and that they were eager students of Dolly’s, and soon learned how to separate the superficial from the meaningful.
Here they are in 1977 singing on Dolly’s prime time TV show:
