Olivia Newton-John

Shortly before her passing from cancer in 2022, the 'Grease' legend recorded a moving rendition of 'Jolene' with Dolly herself.

It featured on Olivia's 'Just The Two Of Us: Duets Volume 1' album.

Parton said: "We've kind of always stayed close through the years and I’m just so proud to be a part of this duets project that she’s doing."
