I could use a little context. I have never heard about this particular thing before. I am but a casual Deadhead, and having growed up in the Midwest, I was well away from the ground zero of all things counterculture. We had a good time nonetheless, back in the day
I gather that there is a bogus show date / setlist / live cuts collection that has endured in the Deadhead world, since once something is out there on the intermess, it's awfully hard to get that toothpaste back into the tube.
Do people actually believe in this incident being attributed to a mass mind control experiment by the DoD / CIA??
