 The Ko-Ko, Nanki-Poo and Yum-Yum exchange from "The Mikado", about lovers being too affectionate in front of another man who loves the woman, is used in the first act of Foggerty's Fairy.The "romantic" old lady, Malvina de Vere, is described as "having the remains of a fine woman about her", as is Ruth in "The Pirates of Penzance".By October 1881, Gilbert was rehearsing "Foggerty's Fairy" at the Criterion.
