The place was packed. Chris Williamson was in the audience at the back. I got a shot, but it was mostly of his forehead as he sat back down after being applauded.
I saw someone with a copy of Media Lens' Propaganda Blitz and asked if they were a regular on the message boards. Turns out that they were not - there was a book stall in the rear selling mostly ML stuff, with a Chomsky and some others.
