Dolly Parton is gearing up for the November release of her first rock 'n' roll album, and if her latest single is any indication, it definitely will not disappoint.

Ahead of the single drop, Parton teased on social media with a behind-the-scenes video and a frenzy-inducing caption:

"Does it get any better than singing 'Let It Be' with @PaulMcCartney who wrote the song?"

🤯

"Not only that, he played piano!"

"Well, it did get even better when @ringostarrmusic joined in on drums, @peterframpton on guitar and @MickFleetwood playing percussion."

🤯🤯

"I mean seriously, how much better does it get?"

She's got a point.

That's right, the two living members of the Beatles: McCartney - who wrote the 1970 hit - and Starr, joined Parton on the "Let It Be" track that was released on Friday.

The classic song begins with Parton singing solo until McCartney joins in on the second line, the two beautifully harmonizing the legendary phrase:

“Speaking words of wisdom, let it be."

Starr's beat accompanies the two after about a minute in and the rest of the song continues with the sound melodic dreams are made of.

Listeners of this collaboration were absolutely blown away.

And they were not only amazed by the McCartney/Starr reunion but also by the addition of Frampton and Fleetwood to the mix.

Parton's Rockstar album - her 49th (!) - is set to drop on November 17. After being inducted into the Rock and Roll Hall of Fame last year, the legendary country music artist decided to record the new genre in order to "earn my keep."

We believe this album will certainly justify the accomplishment... if there ever was any doubt.

Other artists joining Parton on her new venture include: Sting, Steve Perry, Ann and Nancy Wilson, John Fogerty, Joan Jett, Miley Cyrus (also her goddaughter), Debbie Harry, Lizzo, P!nk, Brandi Carlile, Richie Sambora, Steven Tyler, Stevie Nicks, Sheryl Crow, Emmylou Harris, Simon LeBon, Chris Stapleton, Joan Jett, Elton John among others.

What a lineup - November can't get here fast enough!
