If you're heading down to the Astoria this afternoon, be aware that yesterday's gig opened an hour early, and the current rumour from the box office is that the doors are due to open at
6pm instead of the previously scheduled time of 7pm. People have been queuing since 4am this morning, so presumably it's in order to cope with the demand.
As a side note, you might want to pick up a disposable camera on your way down as they have and will be allowed inside the venue.
