The Pirates of Penzance is perhaps Gilbert and Sullivan?s most popular operetta, and tells the story of Frederic, who was apprenticed to a band of tender-hearted, orphaned pirates. A Sullivan Ballad uses a hauntingly simple love duet, from the end of Act 2 ? Ah, leave me not to pine alone and desolate ? which is arranged here as a duet for flute and alto saxophone (or clarinet). Both performers and audience alike will love this beautiful duet.
