Went to watch his 'Harvest Time' documentary at FACT yesterday - footage filmed in California, London, and Tennessee during the filming of 'Harvest' in 1971. Thought it was great - fantastic balance between luxuriating in the music, enjoying the good-spirits between band mates & others during down-time, and gaining an insight into the attention to detail that Young applies to the writing & recording process. Very entertaining brief appearances from Graham Nash and Gil Gilliam. Though the footage is over 50 years old, there were some beautiful shots of the landscape surrounding Young's California barn.
Look out for it as & when its distributed more widely!
