does anyone know anybody who'd be interested/wouldn't mind swapping their tuesday radiohead tickets for a wednesday ticket?

One of my friends has just found out there's a bunch of us going on tuesday 24th, and he has 4 tickets for the 25th that he'd very much like to swap over. Obviously if it has to be done one ticket here, a couple there and a final one yonder, it'll be done that way. Cheers.
