I had to invade my neighbour’s living room to watch (most of) it.
Simple, chronological progression through his professional life; the balance between interviews with the man himself, with rock and pop types and occasional footage and voiceover worked well for me - the ‘drink problem’ got passing mentions but I was very relieved the piece concentrated on his professional life rather than all the usual rock star clinic/arrested/kids/divorce, etc, etc.
I did though wonder whether the absence of the other Walkers was an artistic decision or something else . . .
Thanks for flagging this up, hugely enjoyable and made me interested in the additional content of the cinema version.
