I watched this, amazing. Though I am not really "into" Pink Floyd, it was a great insight of what happened early on.
Take note kids, don't do drugs. Syd will tell you why (er, ok he wont now)
Have a great appreciation of the band now. Even though I did sort of get into them only around the time of the "another brick in the wall", as it was the video that captured me. Was only a boy when the song/video come out, but old enough to like it.
I didn't end up seeing the last 20 minutes as I fell asleep. Dam.
But I did enjoy what I saw.
