Just a bit of additional info in support of John O'B's main news item...
A phone enquiry of the Portobello Film Festival here in London confirmed that the short film about GS, "Nothing But The Magnificent", will be shown this evening at the festival's official opening. Thereafter it seems to be listed for the evening of Monday 13/9.
However, "short" it certainly is, running for only about 6 mins. Both evening showings (i.e. 20/8 & 13/9) will be part of a series of short films, with no strict timetable. Best to time any visits to the bar or toilet carefully, therefore, for fear of missing it!
