There's a review of the Petersburg gig in Russian here:
http://www.kommersant.ru/doc.aspx?fromsearch=eb07a530-1f4e-4abb-a7f9-e7f702bd8898&docsid=1023027The main points - Aqarium played first, and their presence ensured that the gig was sold out - apparently some initially weren't sure why Aqaurim played a short set or who Fairport where, but BG used his 'patronage' to explose Russian Fans to Fairport, something the article says he has wanted to do for a few years - seems like it was pretty successful too. Ric and Chris apparently joined Aqaurium for their last song.
It gives a bit of background about Fairport and their history, L and L, Cropredy.
Rik seemed to enjoy it all, asking the crowd 'Can we come back please?'
And - Aqaurium have been invited to play Cropredy next year!!!
