Nannerl herself was an   apt pupil, no less quick to learn than her brother, and was playing the keyboard with striking virtuosity by the time she was eleven. In that year, 1762, Leopold brought the children to Munich to play before Maximilian III Joseph, Elector of Bavaria. Leopold then took the entire family to Vienna, on a trip that lasted for three months. He had secured invitations from several noble patrons, and within three days of arriving the children were playing at the palace of Count Collalto. Among those present was the Viennese Treasury councillor and future prime minister Karl von Zinzendorf, who noted in his diary that "a little boy, said to be only five-and-a-half years old [Wolfgang was actually nearly seven], played the harpsichord". After an appearance before the Imperial Vice-Chancellor, the Mozarts were invited to the royal court, where the Empress Maria Theresa tested Wolfgang's abilities by requiring him to play with the keyboard covered. During this court visit Wolfgang met the Archduchess Maria Antonia, the future Queen Marie Antoinette of France, who was two months his senior. Mozart's biographer Eric Blom recounts an anecdote of how the Archduchess helped Wolfgang when he slipped on the polished floor; she is supposed to have received a proposal of marriage in return.As the Mozarts began to be noticed by the Viennese aristocracy, they were often required to give several performances during a single day. They were well rewarded for this activity—at the end of their first hectic week in Vienna, Leopold was able to send home the equivalent of more than two years' salary. Their schedule was interrupted when Wolfgang fell ill with scarlet fever, and their former momentum was not regained. Nevertheless, the visit left Leopold eager to pursue further opportunities for social and financial success. On their return to Salzburg, Wolfgang played the harpsichord and violin at a birthday concert for the archbishop, to the evident astonishment of those present.???

input question: Found the following article online, use it to answer the question: What is the first name of the person who released "Give Peace a Chance?"  New strains developed between the band members regarding the appointment of a financial adviser, the need for which had become evident without Epstein to manage business affairs. Lennon, Harrison and Starr favoured Allen Klein, who had managed the Rolling Stones and Sam Cooke; McCartney wanted Lee and John Eastman – father and brother, respectively, of Linda Eastman, whom McCartney married on 12 March. Agreement could not be reached, so both Klein and the Eastmans were temporarily appointed: Klein as the Beatles' business manager and the Eastmans as their lawyers. Further conflict ensued, however, and financial opportunities were lost. On 8 May, Klein was named sole manager of the band, the Eastmans having previously been dismissed as the Beatles' lawyers. McCartney refused to sign the management contract with Klein, but he was out-voted by the other Beatles.Martin stated that he was surprised when McCartney asked him to produce another album, as the Get Back sessions had been "a miserable experience" and he had "thought it was the end of the road for all of us". The primary recording sessions for Abbey Road began on 2 July 1969. Lennon, who rejected Martin's proposed format of a "continuously moving piece of music", wanted his and McCartney's songs to occupy separate sides of the album. The eventual format, with individually composed songs on the first side and the second consisting largely of a medley, was McCartney's suggested compromise. On 4 July, the first solo single by a Beatle was released: Lennon's "Give Peace a Chance", credited to the Plastic Ono Band. The completion and mixing of "I Want You (She's So Heavy)" on 20 August 1969 was the last occasion on which all four Beatles were together in the same studio. Lennon announced his departure to the rest of the group on 20 September, but agreed to withhold a public announcement to avoid undermining sales of the forthcoming album.Released six days after Lennon's declaration, Abbey Road sold 4 million copies within three months and topped the UK charts...???

input question: Found the following article online, use it to answer the question: What is the last name of the person whose third Benhardt play was La Tosca?  The French playwright Victorien Sardou wrote more than 70 plays, almost all of them successful, and none of them performed today. In the early 1880s Sardou began a collaboration with actress Sarah Bernhardt, whom he provided with a series of historical melodramas. His third Bernhardt play, La Tosca, which premiered in Paris on 24 November 1887, and in which she starred throughout Europe, was an outstanding success, with more than 3,000 performances in France alone.Puccini had seen La Tosca at least twice, in Milan and Turin. On 7 May 1889 he wrote to his publisher, Giulio Ricordi, begging him to get Sardou's permission for the work to be made into an opera: "I see in this Tosca the opera I need, with no overblown proportions, no elaborate spectacle, nor will it call for the usual excessive amount of music."Ricordi sent his agent in Paris, Emanuele Muzio, to negotiate with Sardou, who preferred that his play be adapted by a French composer. He complained about the reception La Tosca had received in Italy, particularly in Milan, and warned that other composers were interested in the piece. Nonetheless, Ricordi reached terms with Sardou and assigned the librettist Luigi Illica to write a scenario for an adaptation.In 1891, Illica advised Puccini against the project, most likely because he felt the play could not be successfully adapted to a musical form. When Sardou expressed his unease at entrusting his most successful work to a relatively new composer whose music he did not like, Puccini took offence. He withdrew from the agreement, which Ricordi then assigned to the composer Alberto Franchetti.  Illica wrote a libretto for Franchetti, who was never at ease with the assignment. When Puccini once again became interested in Tosca, Ricordi was able to get Franchetti to surrender the rights so he could recommission Puccini.  One story relates that Ricordi convinced Franchetti that the work was too violent to be successfully staged. A Franchetti family tradition holds that Franchetti gave the work back as a grand...???
