(W.S. Gilbert and Arthur Sullivan, 1879). Frederic, having turned twenty-one, is released from his apprenticeship to the title pirates. Reaching shore for the first time, Frederic falls in love with Mabel, the daughter of Major-General Stanley. Frederic realizes that he was apprenticed until his twenty-first birthday, and, having been born on February 29, he must return to his apprenticeship. Mabel vows to wait for him. The Major-General and the police pursue the pirates, who surrender. The pirates are forgiven, and Mabel and Frederic reunite. As the work is actually a light opera, most of the songs are simply titled after their first lines; the most memorable ones include 'Pour, oh pour, the pirate sherry' and 'I am the very model of a modern Major-General.'
