When I say large group, I mean hundreds of people in a church levels of large group singing church hymns loudly. Not a few dozen inside a room.

Loud singing/talking has been shown to increase coronavirus / droplet transmissions.

You mean Karaoke? A tradition so popular there are million dollar companies providing it as a service?

Again, a small group of people of a dozen people max, all separated in small rooms. Not a church with hundreds all crammed together on pews singing hymns with their masks off.
