When I went into the "autograph booth" on Sunday, he had a big pile of pictures and he kep signing and signing, I bet at the end of the day he would keep signing even in his sleep....
The security guys had a bit of a discussion between them when I asked if he could sign my T-shirt (apparently they thought it was better if i took it off and hand it to him, but eventually he simply leaned over and signed it), they were very careful that people didn't get too close. Oh well, it's their job.
