I once did some programming work for someone who was a Freemason as he happened to note in passing. Also, I am familiar enough with them to recognize that If This Goes On... was about them.
However, I just recently learned that the Shriners, instead of being an independent fraternal organization that one can join directly, are, in fact, an auxilliary organization that (only) Freemasons can join.
What started me off learning about this was finding this video on YouTube:
The official name of the Shriners, as the notes on that video tell us, is: The Ancient Arabic Order Of The Nobles Of The Mystic Shrine.
And then there's the Ancient Egyptian Arabic Order Of The Nobles Of The Mystic Shrine, which had to exist as a separate organization because of certain unhappy characteristics of the bad old days.
Incidentally, it can be seen from the video that the piano roll
is for an 88-key Duo-Art reproducing piano, as is evident from the "snakebite" or "ditto mark" Themodist perforations along the sides. The player piano used to play the roll in the video, however, is not a reproducing piano; but one can see from its tracker bar that it is able to play rolls in both the 88-note and 65-note formats.
