Input: Consider Input: Passage: By the late 1950s, Covent Garden was gradually abandoning its policy of productions in the vernacular; such singers as Maria Callas would not relearn their roles in English. This made it easier for Tucker to point up the difference between the two London opera companies. While Covent Garden engaged international stars, Sadler's Wells focused on young British and Commonwealth performers. Colin Davis was appointed musical director in succession to Gibson in 1961. The repertoire continued to mix familiar and unfamiliar operas. Novelties in Davis's time included Pizzetti's Murder in the Cathedral, Stravinsky's Oedipus rex, Richard Rodney Bennett's The Mines of Sulphur and more Janáček. Sadler's Wells's traditional policy of giving all operas in English continued, with only two exceptions: Oedipus rex, which was sung in Latin, and Monteverdi's L'Orfeo, sung in Italian, for reasons not clear to the press. In January 1962, the company gave its first Gilbert and Sullivan opera, Iolanthe, on the day on which the Savoy operas came out of copyright and the D'Oyly Carte monopoly ended.  The production was well received (it was successfully revived for many seasons until 1978) and was followed by a production of The Mikado in May of the same year.The Islington theatre was by now clearly too small to allow the company to achieve any further growth. A study conducted for the Arts Council reported that in the late 1960s the two Sadler's Wells companies comprised 278 salaried performers and 62 guest singers. The company had experience of playing in a large West End theatre, such as its 1958 sell-out production of The Merry Widow that had transferred to the 2,351-seat London Coliseum for a summer season. Ten years later, the lease of the Coliseum became available.  Stephen Arlen, who had succeeded Tucker as managing director, was the primary advocate for moving the company. After intense negotiations and fund-raising, a ten-year lease was signed in 1968.  One of the company's last productions at the Islington theatre was Wagner's The Mastersingers, conducted by Goodall in 1968, which 40 years later was described by Gramophone magazine as "legendary". The company left Sadler's Wells with a revival of the work with which it had re-opened the theatre in 1945, Peter Grimes. Its last performance at the Rosebery Avenue theatre was on 15 June 1968. 
Question: What are the names of the people that wrote the opera The Mikado?

Output: Gilbert.


Input: Consider Input: Passage: English-Tamil musician M.I.A. (Mathangi "Maya" Arulpragasam) released her second album Kala in 2007, which achieved widespread critical acclaim, and was certified gold in the United States and silver in the United Kingdom. Six months after giving birth to her son Ikyhd in February 2009, she began composing and recording her third studio album in a home studio section of the Los Angeles house she had bought with her partner Ben Bronfman. She used instruments such as the portable dynamic-phrase synthesizer Korg Kaossilator to compose. She took the beat machine and began recording atop Mayan pyramids in Mexico. Much of the work on the album was undertaken at her house in Los Angeles, in what she called a "commune environment", before it was completed in a rented studio in Hawaii. She collaborated with writer-producer Blaqstarr because, in her opinion, "he simply makes good music". M.I.A.'s collaboration with Derek E. Miller of Sleigh Bells on the track "Meds and Feds" prompted her subsequent signing of the band to her label N.E.E.T., and according to Miller, this experience gave him the confidence to record the band's debut album Treats.Her creative partnership with the comparatively unknown Rusko grew from a sense of frustration at what she saw as her now more mainstream associates suggesting sub-standard tracks due to their busy schedules. Diplo worked on the track "Tell Me Why", but at a studio in Santa Monica rather than at the house. He claimed in an interview that, following the break-up of his personal relationship with M.I.A. some years earlier, he was not allowed to visit the house because "her boyfriend really hates me".Tracks for the album were whittled down from recording sessions lasting up to 30 hours. Producer Rusko, who played guitar and piano on the album, described the pair getting "carried away" in the studio, appreciating the "mad distorted and hectic" sound they were able to create. Rusko said "She's got a kid, a little one year old baby, and we recorded his heart beat. We'd just think of crazy ideas". Rusko has described M.I.A. as the best artist he has ever worked with, saying that she had "been the most creative and I really had a good time making music with her". 
Question: What is the name of the person that had their hear beat recorded?

Output: Ikyhd.


Input: Consider Input: Passage: In Billings, Montana, a police officer arrives and discovers Woody Grant walking on the shoulder of the roadway. Woody is picked up by his son David, who learns that Woody wants to go to Lincoln, Nebraska, to collect a million dollar sweepstakes prize he believes he has won. When David sees the sweepstakes letter, he knows immediately that it is a mail scam designed to get gullible people to purchase magazine subscriptions. David brings his father home, where his mother Kate becomes increasingly annoyed by Woody's insistence on collecting the money.
After Woody is picked up again trying to get to Nebraska, David and his brother Ross discuss putting Woody in a retirement home. David pays a visit with his ex-girlfriend, Noel, who returns his belongings and refuses to move back in with him. Their conversation is cut short by a call from Kate reporting that Woody has taken off once again. David retrieves Woody and decides to drive him all the way to Lincoln, much to Kate's dismay.
While in Rapid City, South Dakota, Woody goes on a bender and hits his head while stumbling back to their motel room. David takes him to the hospital to get his head stitched up. David learns that they will be passing through Woody's hometown of Hawthorne, Nebraska, and suggests they spend the night with Woody's family. Woody is against the idea, but they end up going anyway.
They stay with Woody's brother Ray, his wife, and their two sons, Cole and Bart. Woody and David visit a mechanic shop Woody once co-owned, followed by some beers at a bar. When David brings up Woody's alcoholism and problems within the family—with Woody implying that he did not love Kate nor really want children—they get into an argument. At another bar, they meet Ed Pegram, whom the family blames for stealing Woody's air compressor decades ago. Over David's objections, Woody mentions winning the money and the barflies toast his good fortune. The next day, they learn that the news has spread through the town like wildfire. 
Question: Who are Woody and Kate's children?


Output: David.
