I wonder how many people noticed this. Or how many people would notice this, given an hour of exposure on any given Sunday. I know of at least one (me).
The first two are pictures of the bulletin. Notice the hymn numbers. 229 and 622. I turned it over and excitedly drew what you see in the picture above, showed my fellow baritone on the choir, then turned it upside-down and showed him. They were meant to be together.
When the time came for the last hymn, I turned the book upside down and the numbers were right, but unfortunately music and lyrics don’t have rotational symmetry like the number 229 does.
