input: A third milestone in Wodehouse's life came towards the end of 1915: his old songwriting partner Jerome Kern introduced him to the writer Guy Bolton, who became Wodehouse's closest friend and a regular collaborator. Bolton and Kern had a musical, Very Good Eddie, running at the Princess Theatre in New York. The show was successful, but they thought the song lyrics weak and invited Wodehouse to join them on its successor. This was Miss Springtime (1916), which ran for 227 performances--a good run by the standards of the day. The team produced several more successes, including Leave It to Jane (1917), Oh, Boy! (1917-18) and Oh, Lady! Lady!! (1918), and Wodehouse and Bolton wrote a few more shows with other composers. In these musicals Wodehouse's lyrics won high praise from critics as well as fellow lyricists such as Ira Gershwin.  Unlike his original model, Gilbert, Wodehouse preferred the music to be written first, fitting his words into the melodies. Donaldson suggests that this is the reason why his lyrics have largely been overlooked in recent years: they fit the music perfectly, but do not stand on their own in verse form as Gilbert's do. Nonetheless, Donaldson adds, the book and lyrics for the Princess Theatre shows made the collaborators an enormous fortune and played an important part in the development of the American musical. In the Grove Dictionary of American Music Larry Stempel writes, "By presenting naturalistic stories and characters and attempting to integrate the songs and lyrics into the action of the libretto, these works brought a new level of intimacy, cohesion, and sophistication to American musical comedy." The theatre writer Gerald Bordman calls Wodehouse "the most observant, literate, and witty lyricist of his day". The composer Richard Rodgers wrote, "Before Larry Hart, only P.G. Wodehouse had made any real assault on the intelligence of the song-listening public."  In the years after the war, Wodehouse steadily increased his sales, polished his existing characters and introduced new ones. Bertie and Jeeves, Lord Emsworth and his circle, and Ukridge appeared in novels and short stories; Psmith made his fourth and last appearance; two new characters were the Oldest Member, narrating his series of golfing stories, and Mr Mulliner, telling his particularly tall tales to fellow patrons of the bar at the Angler's Rest. Various other young men-about-town appeared in short stories about members of the Drones Club.  The Wodehouses returned to England, where they had a house in London for some years, but Wodehouse continued to cross the Atlantic frequently, spending substantial periods in New York. He continued to work in the theatre. During the 1920s he collaborated on nine musical comedies produced on Broadway or in the West End, including the long-running Sally (1920, New York), The Cabaret Girl (1922, London) and Rosalie (1928, New York). He also wrote non-musical plays, including The Play's the Thing (1926), adapted from Ferenc Molnar, and A Damsel in Distress (1928), a dramatisation of his 1919 novel.  Though never a naturally gregarious man, Wodehouse was more sociable in the 1920s than at other periods. Donaldson lists among those with whom he was on friendly terms writers including A.A. Milne, Ian Hay, Frederick Lonsdale and E. Phillips Oppenheim, and stage performers including George Grossmith, Jr., Heather Thatcher and Dorothy Dickson.

input: Having achieved some fame and prosperity, Verdi began in 1859 to take an active interest in Italian politics. His early commitment to the Risorgimento movement is difficult to estimate accurately; in the words of the music historian Philip Gossett "myths intensifying and exaggerating [such] sentiment began circulating" during the nineteenth century. An example is the claim that when the "Va, pensiero" chorus in Nabucco was first sung in Milan, the audience, responding with nationalistic fervour, demanded an encore. As encores were expressly forbidden by the government at the time, such a gesture would have been extremely significant. But in fact the piece encored was not "Va, pensiero" but the hymn "Immenso Jehova".  The growth of the "identification of Verdi's music with Italian nationalist politics" perhaps began in the 1840s. In 1848, the nationalist leader Giuseppe Mazzini, (whom Verdi had met in London the previous year) requested Verdi (who complied) to write a patriotic hymn. The opera historian Charles Osborne describes the 1849 La battaglia di Legnano as "an opera with a purpose" and maintains that "while parts of Verdi's earlier operas had frequently been taken up by the fighters of the Risorgimento...this time the composer had given the movement its own opera" It was not until 1859 in Naples, and only then spreading throughout Italy, that the slogan "Viva Verdi" was used as an acronym for Viva Vittorio Emanuele Re D'Italia (Viva Victor Emmanuel King of Italy), (who was then king of Piedmont). After Italy was unified in 1861, many of Verdi's early operas were increasingly re-interpreted as Risorgimento works with hidden Revolutionary messages that perhaps had not been originally intended by either the composer or his librettists.  In 1859, Verdi was elected as a member of the new provincial council, and was appointed to head a group of five who would meet with King Vittorio Emanuele II in Turin. They were enthusiastically greeted along the way and in Turin Verdi himself received much of the publicity. On 17 October Verdi met with Cavour, the architect of the initial stages of Italian unification. Later that year the government of Emilia was subsumed under the United Provinces of Central Italy, and Verdi's political life temporarily came to an end. Whilst still maintaining nationalist feelings, he declined in 1860 the office of provincial council member to which he had been elected in absentia. Cavour however was anxious to convince a man of Verdi's stature that running for political office was essential to strengthening and securing Italy's future. The composer confided to Piave some years later that "I accepted on the condition that after a few months I would resign." Verdi was elected on 3 February 1861 for the town of Borgo San Donnino (Fidenza) to the Parliament of Piedmont-Sardinia in Turin (which from March 1861 became the Parliament of the Kingdom of Italy), but following the death of Cavour in 1861, which deeply distressed him, he scarcely attended. Later, in 1874, Verdi was appointed a member of the Italian Senate, but did not participate in its activities.
