@djjd62,
The interview is in the second half of part one, for anyone having difficulty finding it. As I did. (never mind, I found the rest of the program really interesting & informative. Terrific radio!)
I liked the part where Linda Ronstadt talks about the "hardened NY critic" who cried when he heard Kate & Anna sing
Talk to Me of Mendocino. She said she couldn't sing it for quite a time because the song made her cry. It has exactly the some effect on me. Beautiful, moving song.
I thought her description of the McGarrigles as "folk singing aliens in the pop world" was particularly apt.
Rest in peace, Kate. You got your life priorities straight & produced some exquisite music along the way.
