I squatted on the Housmans stall for most of the day, which did very good trade, especially with Verso books. People were taking their politics seriously. But not too seriously. The speaker at the anarchist fiction session, DD Johnston, read a hilarious piece from his novel, about the anarchist bookfair, seeming to prove the opposite of the quote from The Poverty of Student Life that "since the anarchists will tolerate each other, they will tolerate anything".
As I left at 6.30 - the fair still in full swing - I watched the wonderful French brass band Les Judas playing in the courtyard. Emma Goldman famously said* "If I can't dance I don't want to be in your revolution" and the band had many people dancing. What she didn't say was that you had to dance well!
* Actually, she didn't say that at all - see http://sunsite.berkeley.edu/goldman/Features/dances_shulman.html
