can not help on this...which is not suprising...but it reminds me that in the early 80's both the local Midlands BBC and Central TV used to do reports on the Cropredy reunions...very exciting it was to to see FC on local TV... most of my friends had no idea who FC were...the reports were usually before the festival and occasionally post festival...usually the Monday evening...Not seen any coverage for many a year however.
I seem to remember a video clip of a local news report from either 2007 or 2008 being posted on here....so they still do it.
As for the Broughton Castle request, I too can't help although I do have a copy of the original performance on video which (without checking) I think musicfolk put out....
