Especially if there's even just a slight problem that delays it. It shouldn't because the change-overs aren't rushed, but the band are a little late coming out because of traphic, or there's a problem with something, or it just takes them a little longer than expected. There are a lot of thigns that could go wrong.

At least it's a 2h30 set.... That's one thing, and they could always cut down on the time they spend backstage between encors.

I'd have though the curfew would have been more 11, but then it's a lot of people to get out at 11, so maybe that's why it's early.....

i.e I'm guessing if it finishes at 10, the area will be cleared at about 10:30ish at the earliest.
