First of all, let's be clear... I'm not one of the festival organisers, I'm one of the booked guests. They were stuck for someone to put together a website, as the previous webmaster isn't doing it this year.

However, there ARE contact details on the site for booking information, which I'd guess is also valid for programmes, etc...

Box Office Postal Address:
'Cranford'

These details are prominent on the home page of the site.
