A fan's story:
Yes! I got up, threw myself into a borrowed ride with literally 2 minutes notice, no ticket and no way home, grabbed the latest Wall documentary/concert ready from yesterday's non-signing event, withstood a deluge of rain on the line...but managed to get the DVD signed large in silver w/o getting it wet! The 12"x12" flat seemed a truly bad choice in the rain - the DVD had a plastic bag so that was that. I said "Thank you, Mr. Waters" 3 times, but he was yelling about eBay. Someone, perhaps right after me, tried to get two and Waters just drove off. Maybe he did 12 all together. I then waited for it to dry and started working on getting home safely. Got to hear a good chunk of soundchecks too - Breathe, Welcome to the Machine and some bits of others. Saw this show the night before, was comped floor but I took one row off the floor to see the Battersea Power Station fully.
Pictures soon It will go nicely alongside my signed Gilmour DVD!
