I don't get the idea that PIPPIN wouldn't do "Magic to Do" because it gives away anything... it's literally the opening of the show, it's a perfect loss-leader to give away as an enticement to see the rest of the show that follows. Besides, they already did an interactive feature with NYT about that very moment, exploring it in detail, so whether you feel they shouldn't or not, the facts on the ground reveal that this production is more than happy to use their "Magic to Do" as bait. In fact, I'd be shocked if they didn't do that number at the Tonys.
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
