Do you remember the girl's name from the audience who sang with her? I think she was the niece of one of here staff (stage manager?) or what high school she went to. She annouced both on stage.
Stalker alert... I thought she was good enough I would like to see her high school production.
I was so bummed I missed the show. I say go right to the source. KC is very good about answering questions on Twitter. If she doesn't remember it, someone around her knows for sure. Good luck.
While she missed fellow “Wicked” star Idina Menzel at the Opera House by a scant few weeks, she found another duet partner for the friendship ode “For Good” in her tour manager’s 17-year-old daughter, a Rochester teen who delivered a solid performance next to the seasoned performer that led Chenoweth to remark that her harmonies were “spot on.”
Watching her on the Fox stage from upstairs is like watching an ant if you are in the rear.
I was in the St Louis Fox years ago (its twin) & the theater is huge like Radio City huge. The lobby is like a grand russian train station with its red pillars on either side. Georgeous theaters .
