Which cat restores the lights and brings back Old Deuteronomy in Cats?

Mr. Mistoffelees restores the lights and brings back Old Deuteronomy in Cats. After Macavity kidnaps the Jellicle patriarch and escapes by shorting out the stage lights, the cats call on the young magician to repair the crisis.

Mistoffelees is introduced through the number “Magical Mr. Mistoffelees.” He is described as the “original conjuring cat,” a black-and-white tuxedo cat whose supernatural abilities set him apart from the other Jellicles. His featured dance includes the signature Conjuring Turn, traditionally performed as twenty-four consecutive fouettés en tournant.

The scene is important structurally because the Jellicle choice cannot happen while Old Deuteronomy is missing. Mistoffelees uses his magic to restore the lighting and return the patriarch to the junkyard. Old Deuteronomy can then hear Grizabella’s appeal, choose her to ascend to the Heaviside Layer and complete the show’s central ritual. A common mix-up is to credit Munkustrap, who leads the pursuit, or Rum Tum Tugger, who summons Mistoffelees; neither performs the rescue.
