In the UK we are threatened with little socialising well into 2021. I just heard of someone proposing a Messiah performance, one of my seasonal favourites. I know there are many Pub Carol sessions but my routine is The Royal at Dungworth, near Sheffield once a year. Some folks go every Sunday lunchtime after 11th Nov.
But everybody sings and there is not 2m spacing, doubtfully 2mm between those there.
