American Conservatory Theater in San Francisco had to cancel its entire run of the play Toni Stone (one of three women to play professional baseball), but you can buy a ticket to stream it (and keep ACT alive)! I plan to do so:
Gresham College have lots of on-line lectures - also you can attend live for free during normal circumstances, I normally go to a few a year in person and watch a few more on-line - sometimes they have a theatrical one, Michael Pennington gave one on Shakespeare recently . Here's one of topical interest:

I misread this as 'Penzance' and then for some reason my mind jumped to "They've done a drama series that's a gritty re-imagining of the world of Pirates of Penzance??" What the hell, brain. (Er, no offence to anyone here who might live in the real Penzance. I'm sure there's much more to your town than being the setting of PoP. Really.)
Anyway... BroadwayHD is offering a free 7-day trial subscription. You need to actively cancel the subscription before the 7 days are up, or it will be automatically rolled into a paying subscription.
