Late 70's. Circuit Assembly. Talk on "debasing music". "Backwards masking". Specific songs are mentioned. "Stairway to Heaven", "Another Bites the Dust", "Rhiannon", "Hotel California" plus others. Specific groups are mentioned. The Beatles, Led Zeppelin, Fleetwood Mac, The Eagles, Earth, Wind and Fire plus others. An actual clip of Stairway is played backwards for all to hear the Satanic message(All I heard was noise). A list of artists found to be under satanic influence was distributed throught the audience. I don't know if this list orginated from the speaker or if someone else just took advantage of the theme of the talk to hand out their propaganda, but I thought it interesting that copies of the list made it's way through a big part of the audience during this talk. I remember they had in one column the artist name, and in another column the objection about them. One that really stood out was James Taylor. The objection? He spent time in a mental institution. John Denver was on the list. Rocky Mountain High could be about drugs. Peter, Paul & Mary. Puff the Magic Dragon. Drug references. The list went on. Talk about your paranoia. My parents went through all my albums. I lost most of my favorite music because of that one talk.
