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.
