Among professional organists, there are two schools of performance, known colloquially as the with school and the without school -- depending upon whether you play with or without the monkey.
Dead silence. You could have heard crickets chirping in the walls.
So the next week, I show up with a little plush monkey I'd bought, which chittered when you squeezed him in the middle. (I named him Guido -- ten points for anybody who can guess the reference.) And I told the same joke, again -- and made Guido chitter when I did.
More silence. "Tough room," I said.
BTW, I often put Guido on the organ when I play for the occasional service in my current church. Most folks don't even notice him.
