Adele's teases When We Were Young with Tobias Jesso Jr.

UPDATE: Adele debuted the full version of “When We Were Young” early Tuesday morning after teasing the track on Monday. Instead of the studio version, Adele released a live performance taken from London venue The Church, which will air on 60 Minutes Australia.

She previewed the track, which she wrote with Tobias Jesso Jr., to Sirius XM on Monday and said, “It was based on us being older, and being at a party at this house, and seeing everyone that you’ve ever fallen out with, everyone that you’ve ever loved, everyone that you’ve never loved, and stuff like that, where you can’t find the time to be in each other lives. And you’re all thrown together at this party when you’re like 50, and it doesn’t matter and you have so much fun and you feel like you’re 15 again. So that’s the vibe of it really.”

EARLIER: So far, the only hint Adele has given audiences of what’s in store on her upcoming 25 is the wildly successful “Hello,” but she previewed a snippet of another son, “When We Were Young,” in a recently released promo for her segment on 60 Minutes Australia.

The song is a collaboration with singer-songwriter Tobias Jesso Jr., and Adele’s been vocal about her admiration for Jesso, a Canadian musician who released his debut album Goon this past spring: In January, she tweeted a link to the video for Jesso’s “How Could You Babe” along with a note that called the song “fantastic” and an order to “click away.”

In addition to “When We Were Young,” Jesso and Adele also worked together with Sia to write “Alive,” a track originally intended for Adele that ultimately ended up as the lead single for Sia’s forthcoming album, This is Acting.
