"I would go to the studio by day and club by night. I did a lot of ecstasy. A lot. The chorus for Please was written after Bono kept pleading with me to get off the carpet.

- The Edge on Pop
While the band and crew were working on the Joshua Tree album's mixing, Lillywhite's wife, singer Kirsty MacColl, volunteered to set the running order for the album.
