- Adam Clayton
Twenty songs were recorded for Zooropa during the sessions, but ultimately 10 were chosen for the final track listing. One piece that was left off the record was "In Cold Blood", which featured somber lyrics written by Bono in response to the Bosnian War and was previewed prior to the album's release.
