And were there command performances for just one person?
Like, when the Players are commissioned for The Mousetrap, they could be preparing to perform just for Hamlet – would that happen?
We know it’s not so here, as the whole plot hinges on Hamlet getting a particular audience in the room but are there Princes who just want to watch a show by themselves?
I imagine it doesn’t happen much, given how rare ACTUAL solitude would be for royalty. Even if you watched a play alone, you probably also have a handful of staff on hand. And if any dignitaries are around, it would be awfully rude to have a show and not invite them over to watch it.
So performing before a royal personage, as much as it sounds like performing for one person is likely to be a roomful.
