You're right, the print of Out One: Spectre, at least the one which played in NYC, was reported as damaged. As for the London screening of Out 1: Noli Me Tangere, I heard that it went fine. The film was scheduled over a couple of days (obviously!), and so ended up being a quite a unique experience for the viewers. It's certainly difficult to make an immediate judgement on a such a vast and expansive piece of work.
I believe the correct year for Merry-Go-Round is 1978, though it's often listed under either '81 or '83.
