One of the pics features yours truly, on the left, and Matt Buck.
I'm wearing sunglasses because the sun is behind me and that is one big old blank white board. It was giving off quite a glare. It's not some misguided attempt to look cool. That would certainly be offset by the paunch and the dodgy haircut. (Don't worry, I'm OK with my appearance, this is not going to be one of those Lily Allen-style angst blogs!)
There's also a short video on the festival here.
