After sending an item to the residence organ mail list,
I realized that my mention of Boomeria is relevant here also:

If you look closely you will see a picture of chairs underneath the
organ chests.  Kids (and adults) may sit behind the console with
the tracker wires moving above their heads while the organ is being
played.  Gives a whole new meaning to being "into" pipe organs.
