The Drowsy Chaperone

The play-within-a-play uses all the clichéd plot devices of a 1920s musical, including mistaken identity, comedy schtick, phony accents, and dance numbers that don’t quite go with the plot. All the while, the Man in Chair comments, interrupts, and even back-cues Janet at one point. The first act ends with Janet calling the wedding off, to Robert’s dismay and Feldzieg’s delight. But by the time we reach the end, all misunderstandings have been cleared up, not only is Janet’s marriage back on, but she’s joined by three other couples, and everyone dances the big finale.
