The 1975 talked with Zane Lowe about “Happiness” and working with Jack Antonoff:

“I love Jack’s work, and those Lana [Del Rey] records, in particular, like, some of my favorite stuff. So we were talking about that. We became friends talking about production and what I was doing and what he was wanting to do and what I was wanting to do. And then I kind of just thought, ‘Well, this is like a really nice new energy.’ I don’t… because we are so closed, me and George [Daniel], we’ve always been so closed. “Why don’t you like come down to the studio and see what happens?” And then he did. And, then, ever since, we were just great, great friends.”
