I don't know about them using hypnosis in the conventional sense, but I did experience something last year when I went to a couple of meetings after having been out of it and "deprogrammed" for many years. I kid you not! Everybody in the KH seemed robotic right down to the fake smiles. The music seemed weird to me, too. My mother was the piano player years ago when they still used live music. Now, the music has no lift or spirit to it. No one seems to know the songs that well like we did in the old days. They seemed like drones in a hive. I've commented on this before in one of my posts because it was so SPOOKY to me.
Question if anybody knows: Do the KHs HAVE to use the CDs? If a really good piano player wants to furnish the piano and play for the KH, is this allowed nowadays?
