Out of curiosity:
If any show were to perform their Act One (or Act Two) finale from their respective theater, is it possible for them to black out at the end like any other performance? I imagine the telecast would show about 10 seconds of the blackout so we can hear some of the applause, and then it cuts right to commercial. Then, after a few ads, we hear the announcer say something like: "Coming up, [name], [name], [name], and performances by [show] and [show], when the Tony Awards return." The broadcast would then come back after a few more ads.
