Her Downstage Center episode explains it- and is worth checking out.
“I regard the theatre as the greatest of all art forms, the most immediate way in which a human being can share with another the sense of what it is to be a human being.”

If i recall correctly, Charlotte D'Ambroise was starring as Roxie in Chicago, while standing by for Christina Applegate in Sweet Charity, I read a story somewhere of her having to leave mid-performance from Chicago, to take over in Sweet Charity.
"Grease," the fourth revival of the season, is the worst show in the history of theater and represents an unparalleled assault on Western civilization and its values. - Michael Reidel
One of the three current Roxie understudies, Dylis Croman, was also involved in that revival of Sweet Charity. I'm thinking that Dylis was in the cast as an understudy to Christina Applegate. I wonder why Christina never tried the role of "Roxie"?
"Noel [Coward] and I were in Paris once. Adjoining rooms, of course. One night, I felt mischievous, so I knocked on Noel's door, and he asked, 'Who is it?' I lowered my voice and said 'Hotel detective. Have you got a gentleman in your room?' He answered, 'Just a minute, I'll ask him.'" (Beatrice Lillie)
It wasn't simultaneously, but Rhondi Reed did a Matinee of Wicked and the closing night performance of August: Osage County. (Or the opposite of that, I'm fuzzy on the details).

"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
-John Guare, Landscape of the Body
