I just ran across this reference to the "Christy" session:

"A most remarkable session of transpersonal psychotherapy on the record like this occurred in a cavernous convention center in downtown Phoenix, Arizona on December 13, 1985. Several thousand of us at The Evolution of Psychotherapy Conference watched on a large screen as R. D. Laing, M.D. interviewed “Christy,” a woman who was described as paranoid schizophrenic, homeless, and not taking her medication. The two were sheltered off-stage in a small curtained ‘room’ made for the occasion, perhaps to diminish the impact of thousands of observers on them. A live video feed was shown to us as the session unfolded."

Well, I guess that answers the question of whether or not it was being monitored on video. But then, that doesn't mean it was being recorded as opposed to simply being watched on a live closed circuit video feed.

Hmmmmm...
