Again, I very much doubt that LES MISERABLES will be nominated for Best Revival which means it won't be performing.
The performances really depend on what the producers/directors of the shows want people to see on stage.
GREY GARDENS and COMPANY, both shows that have been making most of their promotion based on their leading stars will inevitably try to showcase Ebersole and Esparza, respectively.
When the revival of LA CAGE got nominated (and won) for Best Choreography, they did a number that featured some of Jerry Mitchell's best stuff, so they might do the same with LEGALLY BLONDE.
It really depends. When Chenoweth got raves for YOU'RE A GOOD MAN, CHARLIE BROWN, they made sure that she got to perform her whole number on the Tonys and she had a featured role.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
