I saw this documentary last night at a screening followed by a 'live' discussion between Eric, the director Lili Zanuck and Jools Holland. It was very interesting, not a whole lot I didn't know already about him, and perhaps too much reliance on lingering shots of photographs and home movie footage, but it certainly gave a pretty true version of his life so far. I certainly came away with a lot of respect for him as a man who has survived a lot of hard times, even if a lot of it seemed of his own making. Musically there wasn't a great deal of technical detail or discussion of how he wrote (apart from the song about his son Conor). Overall, I'd highly recommend it as a view of the highs and lows of a legend. I'd be curious about anyone else's views on it.
