I remember a long time ago before the recorded piano music came along,
my congregation had an actual piano that someone would play the song
while we sang.
What do you mean, "a long time ago"? I used to be one of those piano players that the congregation sang along with. Er, um, I hope that doesn't "out" me, so maybe I didn't play... like I haven't already given out enough personal info for the spies to come knocking. But come to think of it, it really was a long time ago that the CO came through and said it was time to stop that and use the recordings.
Even earlier before that I remember when they would assemble an orchestra for the discrap crapventions. And that was back in the day when food service was a huge operation for assemblies and crapventions.
Jeez, now I'm really feeling ancient.
