Watch Adele perform new song When We Were Young on 60 Minutes ahead of 25 album release

With just days to go until the release of her new album 25, Adele has teased fans with a performance of her new song When We Were Young. The singer has recorded a special with Australia's 60 Minutes TV show discussing her comeback to music after three years and the direction of her long-awaited new material.

During the upcoming special, Adele, 27, gives her first performance of the nostalgic ballad, which she explains was written about the relationships in her life that have changed over the years. Speaking in an interview with Sirius XM about the song, Adele 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 kind of vibe of it really." The singer also reveals that her favourite lyric on the song is the line: "You look like a movie / You sound like a song / My god this reminds me of when we were young. 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 kind of vibe of it really."

When We Were Young is the second song to be co-written by Tobias Jesso Jr, and is the second song to be heard from the singer's forthcoming third album. The LP's lead single Hello is currently enjoying its third week at number one on the UK charts after becoming the fastest-selling single of 2015 so far.

Addressing the lengthy hiatus which saw her avoid the public eye, Adele tells the 60 Minutes reporter: "There was quite a long period where I didn't believe in myself," before adding of her fame: "I'm waiting for someone to send me back to Tottenham. I get really nervous, I'm scared. I don't want disappointment." Adele's second album 21, which has been named the greatest album of all time by Billboard, dominated the global charts for months and has sold more than 30 million copies worldwide to date. Commenting on the phenomenal success, Adele questions: "How is it possible that an album kept getting bigger and bigger?"

25 is set for release on 20 November 2015.
