Taylor Swift mines vault of demos

Never-released song with Maren Morris comes out.

Taylor Swift’s grand plan to rerecord her back catalog is moving along, well, swiftly, with the second single off her revamped “Fearless” album. But unlike the last single, this one was never included on “Fearless” in the first place.

On Thursday night, Swift released her updated rendi- tion of “You All Over Me,” the first song the country-pop sensation has resurrected from demos that ended up on the cutting-room floor when “Fearless” came out in 2008. Featured on the track is fellow country artist Maren Morris, who comes in during the wistful chorus.

“One thing I’ve been loving about these From The Vault songs is that they’ve never been heard, so I can experiment, play, and even include some of my favorite artists,” Swift tweeted this week while announcing her latest release. “I’m really excited to have @MarenMorris singing background vocals on this song!!”

Morris celebrated the collaboration on social media as well, expressing her gratitude for both Swift and producer Aaron Dessner, a founding member of rock band The National who also worked closely with Swift on her previous two studio collections, “Folklore” and “Evermore.”

“Whether it’s the Disney vault or the TS vault, you know it’s gonna be good,” Morris wrote on Instagram. “My favorite thing that I don’t get to do very often is to slip into someone’s world and just harmonize. Thank you @taylorswift for having me be a small part of your reimagining of the Fearless era.”
