It was a great evening. The documentary was entertaining and very well-constructed, and the (sold out) night was attended by a broad mix of people: sign writing and design people (some of whom I'd met at my exhibition), young hipster/student types and others - and quite a gender mix too. The event provided so popular that they'd also run it the previous evening, including the live signwriting demos and tryouts before the film started:
In my old days playing rock music we used to joke about the 'hot industry vibe' assigned to particular local bands. Looks like the vibe has well and truly attached itself to the craft of sign writing.
