What time does it show on the tickets? In Europe (at least shows I have been to), the supporting act was on stage at the time shown on tickets (now: in some cities that was 6:30pm, in some cities that was 7:30pm....so it def. varies from a city-to-city, most depending on that whole noise curfue thing).
Opening acts are on about 45 min. and then there is about 45min or so before U2 takes stage.
The tickets say 7 PM. I believe last tour, they came out at approx 9PM
