Well, as you can see there was a break in touring between November 1992 and May 1993. They recorded large part of the album during that break. However, the Zooropa Tour (that was named this way before work on the album had even started) began before they had finished it, so at the beginning of the Zooropa Tour they were touring and recording. The album was released on 3 July (IIRC), so during the tour with the same name.
C ya!
