You just have to wonder what was the source of his unhappiness. He was loved and respected and , for the most part lauded by the critics that matter. His contemporaries in the traddy world had huge respect for him. I know several people went to his gigs and warned me off, because they found him very 'difficult' to understand.
I thought he had some cracking ideas - like The Transports and the Kipling - but I was never keen on the results.

I was aware of his work and always thought we'd meet up somewhere down the line - but we never did.
