Oh, that might have been Mac or Bree, Wandeljw.
I've probably mentioned, too many times, the time I saw Shirley MacLaine. Carol Haney (original B'Way cast) was scheduled to appear in Pittsburgh in Pajama Game, but it wasn't announced at the theatre until the show was about to begin that Carol was suddenly taken ill. The audience began grumbling and then there were some boos, and it took a few awkward moments for the audience to settle down. But after Shirley MacLaine, Carol's understudy, performed "Steam Heat", you could have heard a pin drop and then there was thunderous applause and a standing ovation. It was very exciting.

I have yet to see her equal that performance.
