" If any happens to know what happened, I'm very curious."
So here's the scoop: Victoria Clark was out for vacation, so Jill Abramovitz went on in her place. Unfortunately, Jill lost her voice after singing "It's Possible" and left immediately to see a doctor, and Linda Mugleston took over for Act II. Leslie Flesner then had to cover ensemble tracks for both Jill and Linda.
To me, this is a great example of how well prepared the cast and stage management crew have to be (and WERE) for a large show, as anything can happen and occasionally does. Bravo to all involved in carrying out the tradition of "the show must go on." Sometimes it's just harder than others.
