(evocative of so many nocturnal operatic conspiracies), but best of all is the travesty of the patriotic tune in 'For he is an Englishman!'" Buttercup's Act II song, in which she reveals the dark secret of the baby-switching is preceded by a quote from Franz Schubert's "Erlkönig" and also parodies the opera Il trovatore. Jacobs notes that Sullivan also adds his own humorous touches to the music by setting commonplace expressions in "Donizettian recitative". But on the serious side, he enhances the moments of true emotional climax, as in Josephine's Act II aria, and added musical interest to concerted numbers by "subtly shifting the rhythms and bar groupings." Revisions and cut material Ballad for Captain Corcoran, "Reflect, my child" During rehearsals for the original production, Gilbert added a ballad for Captain Corcoran in which he urged his daughter to forget the common sailor with whom she is in love, because "at every step, he would commit solecisms that society would never pardon." The ballad was meant to be sung between No. 5 and No. 6 of the current score, but it was cut before opening night. The words survive in the libretto that was deposited with the Lord Chamberlain for licensing. Before 1999, all that was known to survive of Sullivan's setting was a copy of the leader violin part. In April 1999, Sullivan scholars Bruce I. Miller and Helga J. Perry announced that they had discovered a nearly complete orchestration – lacking only the second violin part – in a private collection of early band parts. These materials, with a conjectural reconstruction of the partially lost vocal lines and second violin part, were later published and professionally recorded. This piece has now been performed a number of times by amateur and professional companies, although it has not become a standard addition to the traditional scores or recordings. Dialogue for Cousin Hebe In the licensing copy of the libretto, Sir Joseph's cousin Hebe had lines of dialogue in several scenes in Act II. In the scene that follows No. 14 ("Things are seldom what they seem"), she accompanied Sir Joseph onstage and echoed the First Lord's dissatisfaction with Josephine. After several interruptions, Sir Joseph urged her to be quiet, eliciting the response "Crushed again!" Gilbert would later re-use this passage for Lady Jane in Patience. Hebe was also assigned several lines of dialogue after No. 18 ("Carefully on tiptoe stealing")
