Absolutely good stuff. I would have taken a long lens in such a crowd ... Just to capture stuff that would be difficult to foot zoom.
Gary, thank you and I'm glad you mentioned that. In fact, I was carrying Fuji 55-200 as well and I took some of the shots with it, I've updated the exif above. Here's the problem I faced - with a long lens I had to step back. And with that crowd, every time I aimed, someone or other was coming between the lens and the subject continuously. Crowd never stopped.
Net-net: between a Ricoh GR (18mm) and Fuji 55-200 I managed to get few keepers. If Fuji had a prime tele (>120mm), I would love to have one.
