Dolly Parton

Dolly was in the U.K. to promote her upcoming rock album.

It's the fourth single she's released off her upcoming 'Rockstar' album.

On June 8, 1974, Parton's "I Will Always Love You," from her 'Jolene' album, soared to the top of the charts.

It was supposed to be performed alongside "What a Wonderful World" and "Rainbow Connection" from 'The Muppet Movie.'

When Jan. 1 rolls around, people all over the world make their resolutions for the new year, but Parton isn't one of them.

Miley and Dolly came to party and duet.

On Dec. 19, 1980, Parton made her big-screen debut, appearing in the movie '9 to 5'.

It's not quite what you would picture for one of country music's biggest stars.

He nearly gave up on a huge, huge hit.

SING IT, DOLLY!
