Bigger shows can't make money at reduced capacity, but in smaller houses, a few brave producers are trying their luck.
A case in point is in Midtown Manhattan at The Jerry Orbach Theater, which is named for the late TV star who never forgot his roots on the stage.
It is there on the evening of April 9 that the first musical to be staged since the pandemic began will reopen.

The fictional Dunder Mifflin company, so familiar to fans of "The Office" on TV, is back in business Off-Broadway.
And at one of the final rehearsals for "The Office: A Musical Parody," the mood was upbeat thanks to performers who were back at work after more than a year at home.
"We didn't know that we were going to shut down for that long," Devina Sabnis said.
She was on tour with the show when it closed, forcing her to live in her parent's home in South Brunswick, New Jersey. So getting back on stage was life-altering.
"Oh my God, there's nothing like it," she said. "Seeing an audience again, being able to perform."
There is a joy, too, in poking gentle fun at a sitcom Sabnis loved in college while playing a character who inspired her.
"I was obsessed with Kelly because she was the first South Asian person that I really saw on American TV," she said.

In fact, it was while watching Mindy Kaling in the role that Sabnis was convinced to try acting herself.
But returning comes with risks, though Sabnis said she isn't worried.
"I feel extremely safe," she said. "To me, it was like 10 times safer than in-room dining, where you don't actually know who around you is vaccinated or what the air system is like inside."
The performer pointed out the new ventilation system, which is the same one used by NASA, as well as other safety measures including air quality monitors in the lobby.
"The audience will be in pods, separated," she said. "And then on top of that, we are all vaccinated."
Meanwhile, the cast is giving new meaning to the old saying that "the show must go on," a sense of normalcy on West 55th Street -- just a few blocks from bigger Broadway theaters that remain dark.
