Although I didn't get the chance to go to his talk, I did get to meet him, get a Lord of the Rings picture signed and have my photo taken with him. Here are a couple of pics...
He was very busy all weekend but must have signed for nearly 1000 people on the Saturday. I got to Earl's Court at 7.00am so picked up ticket number 213 :)
More pictures from the event are here at my journal, with more photos at my Flickr account.
