The country star, who recorded the song with her mentor Porter Wagoner and Emmylou Harris, jumped at the chance to have another go at the track with Henley.

He says, "She comes in and goes, 'I know this song; I used to do it with Porter'. She sings it once, and she goes, 'Mmm, it’s in a pretty high key for me. I guess I'll just have to rare back and get it'. And, boy, she did. What a voice that girl has, coming out of such a small person."

Henley's new country album also features guest appearances from Sir Mick Jagger, Miranda Lambert, Merle Haggard and Martina MCBride.
