Question: Which of the performers at the 1962 World's Fair was the oldest? Passage 1:"Yoü and I" is a song written and recorded by American singer-songwriter Lady Gaga, taken from her second studio album, Born This Way (2011). She also co-produced it with Robert John "Mutt" Lange. The track samples Queen's "We Will Rock You" (1977) and features electric guitar by Queen's Brian May. Gaga debuted "You and I" in June 2010 during her performance at Elton John's White Tie and Tiara Ball. Footage of the performance appeared on the Internet, and positive response encouraged her to include the song on her setlist for The Monster Ball Tour. She later performed the song on Today to a record crowd in July 2010, and on The Oprah Winfrey Show in May 2011. On August 23, 2011, Interscope Records released the song as the fourth single from the album.
 Passage 2:General Sir Richard Nugent O'Connor, (21 August 1889 – 17 June 1981) was a senior British Army officer who fought in both the First and Second World Wars, and commanded the Western Desert Force in the early years of the Second World War. He was the field commander for Operation Compass, in which his forces destroyed a much larger Italian army – a victory which nearly drove the Axis from Africa, and in turn, led Adolf Hitler to send the German Africa Corps under Erwin Rommel to try to reverse the situation. O'Connor was captured by a German reconnaissance patrol during the night of 7 April 1941 and spent over two years in an Italian prisoner of war camp. He eventually escaped after the fall of Mussolini in the autumn of 1943. In 1944 he commanded VIII Corps in the Battle of Normandy and later during Operation Market Garden. In 1945 he was General Officer in Command of the Eastern Command in India and then, in the closing days of British rule in the subcontinent, he headed Northern Command. His final job in the army was Adjutant-General to the Forces in London, in charge of the British Army's administration, personnel and organisation.
 Passage 3:When Seattle decided to try to put itself on the map with the futuristic Century 21 Exposition — the 1962 World's Fair — high culture was on the agenda, as well as popular entertainment along the lines of "Gracie Hansen's Paradise International" and "Les Poupees de Paris," an adult-themed puppet show, both of which aspired more to a Gay Nineties naughtiness than to anything artistic. The Opera House on the grounds of the center was rebuilt for the occasion (and would be rebuilt again 2001–2003 as McCaw Hall); performers at the fair included Igor Stravinsky, Benny Goodman, and Victor Borge; the Seattle Symphony brought in opera singers and staged Aida. The Fine Arts Pavilion (later the Exhibition Hall) managed to bring in works by Titian, Van Dyck, and Monet, as well as more contemporary pieces by Jackson Pollock, Georgia O'Keeffe, and Alexander Calder and by Pacific Northwest artists Tobey, Callahan, and Graves. There was also a significant exhibition of Asian art and Northwest Coast Indian art. The exposition also commissioned a massive abstract mural by Horiuchi, which still forms the backdrop to the stage at Seattle Center's Mural Amphitheater.
