In the 25 year period from 1871 to 1896, the incomparable William S. Gilbert and Arthur S. Sullivan collaborated on 14 operas that constitute the most frequently performed series of operas in history.

H. M. S.

Higgledy-Piggledy
Gilbert and Sullivan,
Lyrics and music that
Charm as before,
Live on in history
Opera-comically;
Naught can compare with their
Great Pinafore.
