You've seen it in a ton of movies: before the big climax at the end there's the quiet scene of preparation. WWII soldiers are reading letters from home before D-Day; Lighting McQueen gets new tires and a paint job before the big race; the baseball pitcher massages his arm; Greek soldiers polish their swords before the final battle. . .
I have no swords to polish (our swords are fine the way they are, but I do have some costume fixes to perform. Meanwhile, hopefully, the kids in the show have gone over their lines again and their lyrics, and their dance steps, and will get a good night's sleep and eat a good breakfast tomorrows, because tomorrow at 10:30 a.m., it's SHOW TIME!
