From an R.G. Bethany, subject line of "Peace":
The Movie "HAIR" is Psychological Anti-Warfare at its finest. Here's how it works. Two hours of very exciting music and dance. Nothing bad is said or implied. Everything is happy. You will notice alot of movement in every scene. Several things are always moving. You are being conditioned. Knowing this does not matter. Then the series of scenes at the end and…BAM. It hits you hard. Remember this is Psychological Anti-Warfare.
