### I was sort-of daydreaming...

so I don't quite recall how much there is...

but, well, Here is a lovely recording

what struck me most about it is the drums. They can particularly be heard around the final Amen, but there's somewhat more.

Here's another I just can't get out of my head at the moment

I blame Robert Reilly.

Over the summer, I was contemplating an arrangement of things like the following: start with a special square
$$\begin{array}{ccc} A & \to & B \\ \downarrow & \ulcorner & \downarrow \\ C & \to & P \end{array}$$
There is then some delightful nonsense which guarantees the following special squares
$$\begin{array}{cccccc} & E & \to & F & \to & *\\ & \downarrow & \lrcorner & \downarrow & \lrcorner & \downarrow \\ & A & \to & B & \to & P \\ E & \to & G & \to & * \\ \downarrow & \lrcorner & \downarrow & \lrcorner & \downarrow \\ A & \to & C & \to & P \\ & & & E & \to & F \\ & & & \downarrow & \ulcorner & \downarrow \\ & & & G & \to & * \end{array}$$
That last one is the really-special one, because of where the $*$ sits in it. It makes $E$ rather simpler than it otherwise might have been... But that's a story for another day.
