Dolly Parton's final vocal recording appears on U2's new album, Carnaval de Luz, due November 13. The band announced today that Parton, who died in August at age 80, duets with Bono on the album-closing track "Torn."

Parton recorded the song in June. She shares writing credits with the band and Snow Patrol's Johnny McDaid.

"When she got ill," Bono tells Rolling Stone in interviews for an upcoming feature, "she got out of her bed to sing this song. And you can hear that. And I can't even listen to it now."

The collaboration nearly took a different shape. Bono initially approached Parton for a still-unreleased side project inspired by Irish folk music, and played her a few sketches over the phone. "She said, 'That's a little too Irish for me,'" Bono recalls. "But she said, 'I got this song. It's called "Torn," and do you wanna see where you can take it somewhere else, maybe?'"

Bono and McDaid rewrote the lyric around a mother watching her family split apart, and Parton agreed to sing the new version. "She sang her heart out," says Bono. "And I cannot believe that's an 80-year-old woman."

The track carries the fingerprints of two longtime U2 associates. Daniel Lanois plays pedal steel on the recording. Drummer Larry Mullen Jr. added a part inspired by a Lanois production, Bob Dylan's "Most of the Time."

Parton heard and approved the final mix. "Dolly loved it," says the album's producer, Garret "Jacknife" Lee. "She was so proud of her vocal and the recording. She was thrilled with it. We were very nervous that she might not approve, or would be uncomfortable with it, but she loved it."

For Bono, the loss is still settling in. "It's very moving to have had these intimacies with such a figure," he says. "The fact that they're not there now, in any way you can call back, other than through her songs, is very sobering."

"Torn" is not the only Parton recording to surface since her death. The just-released Stanley Brothers tribute "Bound to Ride," a separate posthumous track, was recorded much earlier, circa 2022.

Carnaval de Luz, the album that now closes Parton's seven-decade recording career, arrives November 13.
