There are some theatrical gems online at present - including this excellent play about the long forgotten WW1 poet Charles Hamilton Sorley from the tiny Finborough Theatre.  It's just a room over a pub - if you're in the front row you need to tuck your feet in so you don't trip up the cast! I can't imagine that social distancing could ever be feasible in theatres like this; the seating capacity is only 50 and they need full houses to survive. I can honestly say that I've never, ever seen a play here that I haven't enjoyed!
