Deliberate mistake: The song "If you give me your attention" (from "Princess Ida") and the Mikado's song (from "The Mikado," of course) are performed with their central verses omitted. This was no doubt to save time and, in the case of the Mikado's song, to avoid inclusion of the line "is blacked like a ni**er" (altered in 1948 to "is painted with vigour").
