r21, I posted that story a few years ago. It wasn't a fly-over city, it was in San Francisco!
I was in this interactive murder-mystery show- lots of audience participation - and she was brought in to bring a "name" to the show.
From the beginning, we could tell she was a loon. Just very dramatic, showing off her little boy's headshot, bitching about this lawsuit against Haim Saban (who ripped her off from royalties, etc).
Anyway, rehearsals were tough, because the directors were always trying to throw us curveballs as they prepared us to be in front of the "audience"
One day, Kathy says to me, "I've got a bit of a headache" and on we go with rehearsal. The directors were actually being a bit tough on me and some of the other actors, not Kathy, but she suddenly runs offstage!
The director sends the stage manager backstage to see if she's ok and we continue.
All of a sudden we hear this bloodcurdling scream, "MOMMY!!! I WANT MY MOMMY!!!! AAHAHHAHAA!!!" It was unreal.
Needless to say, the director sent us outside for a bit.
We came back in, there's Kathy, sitting in the audience, eating a bear claw (I'll never forget that). After a minute, she came back onstage and said to me, "Well, my headache is gone."
They fired her the next day.
The stage manager told me later that when he went backstage, Kathy was lying on the ground in a fetal position and when he went to touch her to see if she was ok, she jumped up and stared past him as if he wasn't there. And then she started to scream for her mommy.
It's probably the most bizarre experience I'd ever had in the theater (and there have been a few!)
