Workprint
I saw a workprint of that movie at a festival a few years back and I remember many bits and pieces that weren't included in the final version. For example the Ramones talked about the movie Rock & Roll Highschool and how they hated it. It also featured a much more negative portrait of Phil Spector...
I wish they kept more of that stuff in the movie and I wouldn't complained if the movie was much much longer.
