Adeline

This song is about a Tasmanian Devil's unrequited love for a girl called Adeline. Ooh, my Adeline, ooh Down in Tasmania Where the devil's jaws are far too weak To tear you away Ooh, I wish you well Alt-J tweeted an explanation of the song when it was made available on May 24, 2017: "A Tasmanian devil falls in love with a woman as he watches her swim. Enjoy."

Speaking on Zane Lowe's Beats 1 show, keyboardist Gus Unger-Hamilton revealed that ideas for the track originated when the band was on tour. "It initially started to be written in Australia, and was one of the ones we'd do in soundcheck quite a lot - just like playing with little bits of it and trying it out, trying to remember what was good with recordings and voice memos," Unger-Hamilton said. "Then we'd come back to it time and time again, and when we came back to the UK to make album number three, we knew 'Adeline' was going to be a song that would be on that record. So we got together, unwrapped all of our ideas and looked at what we had - and then we put it all together."

The song incorporates an adaptation of a melody from Hans Zimmer's soundtrack to The Thin Red Line.
