Never heard of such a thing. Are you making this up or what?
No, he's not making it up. The list actually was created (according to my understanding) for the Bethel family. Eventually, the list was photo copied and made it's way into the hands of the rank & file. I specifically remember seeing a phot copy of it. ( I think it was around 1983 or so) This list was not intended to be distributed in the congregations; as it was a Bethel guideline for the Bethel family. But, individual Witnesses took it upon themselves to try to enforce this guideline in the congregations.
In fact, just as a side note, Bethel conducted a "sweep" of all of the music owned by Bethelites. I know this to be true, because I served at Bethel and remember several overseers telling us stories about it. (I'm not sure what year this was, it was much later on) All Bethelites were to collect all of their music and allow Bethel Elders or Home Overseers to look through it. Any music that was found to be "objectionable" had to be thrown out. Any Bethelite who refused to throw away such objectionable music had to leave Bethel.
Here's where it gets interesting. Many overseers in Bethel; in their conversations with family and friends back home, mentioned various groups and albums that were found to be "objectionable" by Bethel. What do you think happened next? Several elders and COs started flapping their jaws about this music and how it was not acceptable for any Witnesses. Again, they took guidelines intended for the Bethel family and tried to beat the rank & file over the head with it.
