Although electric guitars and drums have driven the choirs and organs out of most Protestant churches these days.

I'm OK with dumping the pipe organs, they had their time but as a musical instrument they're very limited and muddy sounding. Just use a nice piano. On the other hand there is nothing better than a great choirs, no instruments needed.

I disagree. I love organ music. However, choirs and singing groups can, indeed, sound great without instrumentation, as demonstrated by the Song Spinners, the Ken Darby Singers, and other vocal groups who managed to make hits in the early 1940’s when the instrumentalists were on strike.
