Question: Passage: 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. 
Question: Who played the keyboard with striking virtuosity?

Answer: Wolfgang.


Question: Passage: Lennon first met Yoko Ono on 9 November 1966 at the Indica Gallery in London, where Ono was preparing her conceptual art exhibit. They were introduced by gallery owner John Dunbar. Lennon was intrigued by Ono's "Hammer A Nail": patrons hammered a nail into a wooden board, creating the art piece. Although the exhibition had not yet begun, Lennon wanted to hammer a nail into the clean board, but Ono stopped him. Dunbar asked her, "Don't you know who this is? He's a millionaire! He might buy it." Ono had supposedly not heard of the Beatles, but relented on condition that Lennon pay her five shillings, to which Lennon replied, "I'll give you an imaginary five shillings and hammer an imaginary nail in." Ono subsequently related that Lennon had taken a bite out of the apple on display in her work Apple, much to her fury.Ono began to telephone and visit Lennon at his home. When Cynthia asked him for an explanation, Lennon explained that Ono was only trying to obtain money for her "avant-garde bullshit". While his wife was on holiday in Greece in May 1968, Lennon invited Ono to visit. They spent the night recording what would become the Two Virgins album, after which, he said, they "made love at dawn". When Lennon's wife returned home she found Ono wearing her bathrobe and drinking tea with Lennon who simply said, "Oh, hi." Ono became pregnant in 1968 and miscarried a male child on 21 November 1968, a few weeks after Lennon's divorce from Cynthia was granted.Two years before the Beatles disbanded, Lennon and Ono began public protests against the Vietnam War. They were married in Gibraltar on 20 March 1969, and spent their honeymoon at the Hilton Amsterdam, campaigning with a week-long Bed-In for Peace. They planned another Bed-In in the United States but were denied entry, so they held one instead at the Queen Elizabeth Hotel in Montreal, where they recorded "Give Peace a Chance". They often combined advocacy with performance art, as in their "Bagism", first introduced during a Vienna press conference. Lennon detailed this period in the Beatles song "The Ballad of John and Yoko". Lennon changed his name by deed poll on 22 April 1969, adding "Ono" as a middle name. The brief ceremony took place on the roof of the Apple Corps building, where the Beatles had performed their rooftop concert three months earlier. Although he used the name John Ono Lennon thereafter, official documents referred to him as John Winston Ono Lennon, since he was not permitted to revoke a name given at birth. The couple settled at Tittenhurst Park at Sunninghill in Berkshire. After Ono was injured in a car accident, Lennon arranged for a king-size bed to be brought to the recording studio as he worked on the Beatles' last album, Abbey Road.Ono and Lennon moved to New York, to a flat on Bank Street, Greenwich Village. Looking for somewhere with better security, they relocated in 1973 to the more secure Dakota overlooking Central Park at 1 West 72nd Street. 
Question: What are the last names of the two individuals who spent the night recording what would become the Two Virgins album?

Answer: Lennon.


Question: Passage: In August 1953, Presley checked into the offices of Sun Records. He aimed to pay for a few minutes of studio time to record a two-sided acetate disc: "My Happiness" and "That's When Your Heartaches Begin". He later claimed that he intended the record as a gift for his mother, or that he was merely interested in what he "sounded like", although there was a much cheaper, amateur record-making service at a nearby general store. Biographer Peter Guralnick argued that he chose Sun in the hope of being discovered. Asked by receptionist Marion Keisker what kind of singer he was, Presley responded, "I sing all kinds." When she pressed him on who he sounded like, he repeatedly answered, "I don't sound like nobody." After he recorded, Sun boss Sam Phillips asked Keisker to note down the young man's name, which she did along with her own commentary: "Good ballad singer. Hold."In January 1954, Presley cut a second acetate at Sun Records—"I'll Never Stand in Your Way" and "It Wouldn't Be the Same Without You"—but again nothing came of it. Not long after, he failed an audition for a local vocal quartet, the Songfellows. He explained to his father, "They told me I couldn't sing." Songfellow Jim Hamill later claimed that he was turned down because he did not demonstrate an ear for harmony at the time. In April, Presley began working for the Crown Electric company as a truck driver. His friend Ronnie Smith, after playing a few local gigs with him, suggested he contact Eddie Bond, leader of Smith's professional band, which had an opening for a vocalist. Bond rejected him after a tryout, advising Presley to stick to truck driving "because you're never going to make it as a singer".Phillips, meanwhile, was always on the lookout for someone who could bring to a broader audience the sound of the black musicians on whom Sun focused. As Keisker reported, "Over and over I remember Sam saying, 'If I could find a white man who had the Negro sound and the Negro feel, I could make a billion dollars.'" In June, he acquired a demo recording by Jimmy Sweeney of a ballad, "Without You", that he thought might suit the teenage singer. Presley came by the studio, but was unable to do it justice. Despite this, Phillips asked Presley to sing as many numbers as he knew. He was sufficiently affected by what he heard to invite two local musicians, guitarist Winfield "Scotty" Moore and upright bass player Bill Black, to work something up with Presley for a recording session. 
Question: What is the name of the quartet that the artist failed to join after an audition?

Answer:
the Songfellows.
