I won't be there.
I've been busy being ill all week and while I made it in to work today, I now regret it enough that I'm almost certainly not going in again tomorrow. And even if I was well enough, I've been asked to stand in for someone for a gig on Saturday night here in Sheffield, which is far cheaper than meating (I'll probably get paid about what it would have cost me to get there and receive as much free booze as I would have had to buy had I gone to London).
So it looks like this time, cheap, easy local fun for the skint ill person wins.
Sorry chaps.
