Given the following context: During his marriage to Cynthia, Lennon's first son Julian was born at the same time that his commitments with the Beatles were intensifying at the height of Beatlemania. Lennon was touring with the Beatles when Julian was born on 8 April 1963. Julian's birth, like his mother Cynthia's marriage to Lennon, was kept secret because Epstein was convinced that public knowledge of such things would threaten the Beatles' commercial success. Julian recalled that as a small child in Weybridge some four years later, "I was trundled home from school and came walking up with one of my watercolour paintings. It was just a bunch of stars and this blonde girl I knew at school. And Dad said, 'What's this?' I said, 'It's Lucy in the sky with diamonds.'" Lennon used it as the title of a Beatles song, and though it was later reported to have been derived from the initials LSD, Lennon insisted, "It's not an acid song." Lennon was distant from Julian, who felt closer to McCartney than to his father. During a car journey to visit Cynthia and Julian during Lennon's divorce, McCartney composed a song, "Hey Jules", to comfort him. It would evolve into the Beatles song "Hey Jude". Lennon later said, "That's his best song. It started off as a song about my son Julian ... he turned it into 'Hey Jude'. I always thought it was about me and Yoko but he said it wasn't."Lennon's relationship with Julian was already strained, and after Lennon and Ono moved to New York in 1971, Julian did not see his father again until 1973. With Pang's encouragement, arrangements were made for Julian and his mother to visit Lennon in Los Angeles, where they went to Disneyland. Julian started to see his father regularly, and Lennon gave him a drumming part on a Walls and Bridges track. He bought Julian a Gibson Les Paul guitar and other instruments, and encouraged his interest in music by demonstrating guitar chord techniques. Julian recalls that he and his father "got on a great deal better" during the time he spent in New York: "We had a lot of fun, laughed... answer the following question: What is the last name of the person that encouraged Lennon's first son to see Lennon more?

Q: Given the following context: Byzantines were avid players of tavli (Byzantine Greek: ), a game known in English as backgammon, which is still popular in former Byzantine realms, and still known by the name tavli in Greece. Byzantine nobles were devoted to horsemanship, particularly tzykanion, now known as polo. The game came from Sassanid Persia in the early period and a Tzykanisterion (stadium for playing the game) was built by Theodosius II (r. 408450) inside the Great Palace of Constantinople. Emperor Basil I (r. 867886) excelled at it; Emperor Alexander (r. 912913) died from exhaustion while playing, Emperor Alexios I Komnenos (r. 10811118) was injured while playing with Tatikios, and John I of Trebizond (r. 12351238) died from a fatal injury during a game. Aside from Constantinople and Trebizond, other Byzantine cities also featured tzykanisteria, most notably Sparta, Ephesus, and Athens, an indication of a thriving urban aristocracy. The game was introduced to the West by crusaders, who developed a taste for it particularly during the pro-Western reign of emperor Manuel I Komnenos. answer the following question: What five cities had a tzykanisteria?
A: Constantinople

Given the following context: In March 1957, John Lennon, then aged sixteen, formed a skiffle group with several friends from Quarry Bank High School in Liverpool. They briefly called themselves the Blackjacks, before changing their name to the Quarrymen after discovering that a respected local group was already using the other name. Fifteen-year-old Paul McCartney joined them as a rhythm guitarist shortly after he and Lennon met that July. In February 1958, McCartney invited his friend George Harrison to watch the band. The fifteen-year-old auditioned for Lennon, impressing him with his playing, but Lennon initially thought Harrison was too young for the band. After a month of Harrison's persistence, during a second meeting (arranged by McCartney), he performed the lead guitar part of the instrumental song "Raunchy" on the upper deck of a Liverpool bus, and they enlisted him as their lead guitarist.By January 1959, Lennon's Quarry Bank friends had left the group, and he began his studies at the Liverpool College of Art. The three guitarists, billing themselves at least three times as Johnny and the Moondogs, were playing rock and roll whenever they could find a drummer. Lennon's art school friend Stuart Sutcliffe, who had just sold one of his paintings and was persuaded to purchase a bass guitar, joined in January 1960, and it was he who suggested changing the band's name to Beatals, as a tribute to Buddy Holly and the Crickets. They used this name until May, when they became the Silver Beetles, before undertaking a brief tour of Scotland as the backing group for pop singer and fellow Liverpudlian Johnny Gentle. By early July, they had refashioned themselves as the Silver Beatles, and by the middle of August shortened the name to The Beatles.Allan Williams, the Beatles' unofficial manager, arranged a residency for them in Hamburg, but lacking a full-time drummer they auditioned and hired Pete Best in mid-August 1960. The band, now a five-piece, left four days later, contracted to club owner Bruno Koschmider for what would be a... answer the following question: What was the full name of the person he performed the lead guitar part of the instrumental song "Raunchy"?
