Nope, it was Rotterdam. IIRC, the band did a full dress rehearsal on 7 May 1993, in which Bono wore the red fly suit. You have to keep in mind that the band hadn't performed in concert for 6 months and that they had changed the design of the show a bit (the burning crosses -> swastika sequence in Bullet..., less Trabants, etc.), so they probably wanted to be sure they still had 'it'.
C ya!
