Looks like this will be unofficial and just some of us going as a group of friends. What I'll probably do is nip down to the box office at some point next week (Wednesday?) and book 10 tickets which will be first come first served bought off me. I will need the money ASAP.
I would do it through the SU, but there seems to be no way of doing it in a timescale which guarantees we'll even be able to book seats together.
10 is less than the sum of people interested, but I see it as more likely people will drop out than suddenly decide to come along.
