Now streaming on YouTube etc. Only just got to it as distracted by some work. Seems to be working as a 'thing' ? Assume it'll remain online after live stream, but looking like a decent 3hrs of tankery.
It seems to be David Willey and Richard Cutland chatting with a range of previously taken videos. However this is well-crafted video footage from generally up close, E g. The video of the Vickers Medium which is no longer used as a runner. As I commented on Twitter, you don't get as close-up a view of the tanks when you are at Tank Fest.
