Based on that pricing structure, it would be a no, especially for only a 90 minute set.
The O2 is not the greatest venue for concerts, though AEG evidently think it is.

A residency would become incredibly dull.......
At an absolute push I would go once, and that would only be if I knew there would be no standard UK tour in the summer.

I would rather pay £50 for an outdoor show, knowing I'd get 2 1/2 hours, plus some good support.
However, I also know that we're going to get ripped off again and charged around £75 for a ticket for stadium gigs, regardless of being near the stage or right at the back.

We've already decided that when UK gigs are announced we're not going to buy tickets until the very last minute.
If we miss out, we miss out.... Been disappointed with the last two tours and are ready to make the next one our last.
