It does look good EC - it's called 'Cracked Actor' - the blurb in the TV guide says there's plenty live music, but it shows a rock star at the height of his powers while in the grip of cocaine addition and the it's the behind the scenes snapshot of his fragile state that is most illuminating.
I saw something on YouTube last week. It was a fans review of his music collection which included a lot of Bowie albums. He made reference to the alleged fact that Bowie makes albums in threes (although not explicitly publicised).
He highlighted the albums made during heavy drug use, the Berlin trilogy and the crap trilogy!
Now that is one fans view, but it does make me want to know more. The documentary is a must - I have no recorder, so watching it is the way for me.
