Meanwhile, the Broadway-bound Thoroughly Modern Millie has been experiencing technical and personnel glitches. A computer problem caused the turntable set to jam, just minute before the first performance on Oct. 6, and so the cast had to sing the show with the orchestra but without the benefit of a set. This came on top of a last-minute replacement of the leading lady.

Producers have pushed back its first previews for the fourth time in a row. Now the show is set to open 7 PM Sunday, Oct. 22. The first preview performances began Tuesday, Oct. 10.
