Hoot, I remember dropping Walter off at BBC studio at White City in West London where he was to be filmed with Karl (or should that be Fred) Dallas and The Albion Band(?)
Walter was somewhat non-committal about it later, but can't remember it being issued.
Wasn't he also included in 'The Other Music'?
Can't understand why John Cohen made such a mess of it - remember the fixation with the milk bottle on Walter's table; and when the camera panned slowly down from "the top of his head right down to the soles of his feet" while he was singing Broomfield Hill - oh dear - not his finest moment!!
John made such good films; I remember two on a South American family - masterpieces.
