From Pornokitsch tipster Pete:
"There's a book fair on 16 May and last time I went there were loads of old Penguins. It's at St Giles - the old church stranded in the Barbican. At the same time there's a glorious concert given by organ scholars who use the massive church organ. The music starts at 15.30 but I bet the fair begins earlier [11am]. www.organschool.com"
Barbican + Organ music + old paperbacks.
