Speaking with The Hollywood Reporter about the project, Parton says that Nicks stayed with Sheryl Crow in Nashville for four days while recording the duet and that the pair swapped "personal stories and stuff that I won’t tell here."
“She stayed in Nashville for four days, which was great. Getting in the studio with her was great,” Parton explained. “We talked a lot. She stayed over with Sheryl Crow; they’re friends. She would come in down the studio, and we did get a chance to talk about the business.”
"We talked about before she started with Fleetwood Mac," she says. "We did talk about the business. We talked about our backgrounds. In fact, our song, What Has Rock and Roll Ever Done to Me, she said, 'This a song I wrote back when we were in the heat of our stuff.' She said, 'It’s a song I love but they didn’t think it was good enough to be on a record.'
"She said, “I have an old demo of it. Can we do this one, because I wrote it about someone I was involved with that was also in the rock ’n’ roll field when we had an affair?' She wrote that about their relationship because they had fun about it. 'What has rock ’n’ roll ever done for you?' They said, 'Well, everything', because they were both famous and rich. She just said, 'I just love this song. I’d like to do it just to commemorate that time in my life and that person'."
Rockstar is set for release on November 17. A number of singles have already been released from the 29-track album, including World On Fire, and Bygones, which features Judas Priest's Rob Halford.
