I got two standing tickets for tonight going spare, £30 each (which is what I paid), give me a ring if you're interested.
The only 'catch' is that I really can't be very flexible on the picking up arrangements, I'll get back to Clapham North tube at 8pm but I can't get any closer to Hammersmith than that, sorry. if you can do that, they're yours!
I'm punctual though and Cave won't be on till at least 9pm so you won't miss him.
My number is 07796 430664.
