When We Were Young is expected to be her second official single from the album and the 27-year-old performed the track in full as part of an epic session at The Church in London.

Adele has previously said the track, co-written with Tobias Jesso Jr, is her favourite on the album.

25 will be released worldwide on November 20, and features further co-writes with Max Martin, Ryan Tedder and Bruno Mars.
