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 theatre did the Sadler's Wells company perform prior to 1968?

Ex Output:
Islington theatre.

Passage: Bush starred in the 1990 black comedy film Les Dogs, produced by The Comic Strip for BBC television. Bush plays the bride Angela at a wedding set in a post-apocalyptic Britain. In another Comic Strip Presents film, GLC, she produced and sang on the theme song "Ken". The song was written about Ken Livingstone, the leader of the Greater London Council and future mayor of London, who at the time was working with musicians to help the Labour Party garner the youth vote.Bush wrote and performed the song "The Magician", using a fairground-like arrangement, for Menahem Golan's 1979 film The Magician of Lublin. The track was scored and arranged by Michael Kamen. In 1986, she wrote and recorded "Be Kind to My Mistakes" for the Nicolas Roeg film Castaway. An edited version of this track was used as the B-side to her 1989 single "This Woman's Work". In 1988, the song "This Woman's Work" was featured in the John Hughes film She's Having a Baby, and a slightly remixed version appeared on Bush's album The Sensual World. The song has since appeared on television shows, and in 2005 reached number-eight on the UK download chart after featuring in a British television advertisement for the charity NSPCC.In 1999, Bush wrote and recorded a song for the Disney film Dinosaur, but the track was not included on the soundtrack. According to the winter 1999 issue of HomeGround, a Bush fanzine, it was scrapped when Disney asked her to rewrite the song and she refused. Also in 1999, Bush's song "The Sensual World" was featured prominently in Canadian filmmaker Atom Egoyan's film "Felicia's Journey".In 2007, Bush was asked to write a song for The Golden Compass soundtrack which made reference to the lead character, Lyra Belacqua. The song, "Lyra", was used in the closing credits of the film, reached number 187 in the UK Singles Chart and was nominated for the International Press Academy's Satellite Award for original song in a motion picture. According to Del Palmer, Bush was asked to compose the song on short notice and the project was completed in 10 days. 
Question: What is the last name of the person who wrote and recorded "Be Kind to My Mistakes" ?

Ex Output:

Passage: The history of Gilwell Park can be traced to 1407, when John Crow owned Gyldiefords, the land that would eventually become Gilwell Park. Between 1407 and 1422, Crow sold the land to Richard Rolfe, and the area became known as Gillrolfes, "Gill" being Old English for glen. Following Rolfe's death in 1422, different sections of the property came to be called "Great Gilwell" and "Little Gilwell". The two areas were named after the Old English "wella", or spring. A farmhouse has stood at Gilwell Farm ever since.
Around this time, an adjoining 5.6 hectares (14 acres) property was purchased by Richard Osborne. In 1442, he built a large dwelling called Osborne Hall, which stood for 300 years. Legend has it that in the early 16th century, King Henry VIII owned the land and built a hunting lodge for his son Edward. Around 1736 the highwayman Dick Turpin began using Gilwell's forests to conceal himself and for ambushing travellers and freight along roads leading into London.In 1754, William Skrimshire purchased Great Gilwell, Little Gilwell, and half of Osborne's estate, including Osborne Hall. Skrimshire demolished Osborne Hall and built a new residence, which he also called Osborne Hall. That building is now called the White House. Timbers in the White House can be dated to this time, but not to any previous era. Leonard Tresilian (?–1792) bought the estate in 1771 and expanded the land holdings and size of the residence.
Tresilian's first wife, Margaret Holland, died young after bearing three daughters. He then married Elizabeth Fawson. Desiring that Gilwell pass on to his eldest daughter, also named Margaret (1750 – c.1844), Tresilian drew up a detailed prenuptial agreement with Fawson's father. By the time of Tresilian's death in 1792, the younger Margaret had married William Bassett Chinnery (1766–1834), the elder brother of the painter George Chinnery. 
Question: What is the name of the person that Leonard Tresilian wanted to leave his estate to?

Ex Output:

Margaret.
