input: Please answer the following: Given the following context:  The company, retaining the title "Sadler's Wells Opera", opened at the Coliseum on 21 August 1968, with a new production of Mozart's Don Giovanni, directed by Sir John Gielgud. Though this production was not well received, the company rapidly established itself with a succession of highly praised productions of other works. Arlen died in January 1972, and was succeeded as managing director by Lord Harewood.The success of the 1968 Mastersingers was followed in the 1970s by the company's first Ring cycle, conducted by Goodall, with a new translation by Andrew Porter and designs by Ralph Koltai.  The cast included Norman Bailey, Rita Hunter and Alberto Remedios. In Harewood's view, among the highlights of the first ten years at the Coliseum were the Ring, Prokofiev's War and Peace, and Richard Strauss's Salome and Der Rosenkavalier. The company's musical director from 1970 to 1977 was Charles Mackerras. Harewood praised his exceptional versatility, with a range "from The House of the Dead to Patience." Among the operas he conducted for the company were Handel's Julius Caesar starring Janet Baker and Valerie Masterson; five Janáček operas; The Marriage of Figaro with pioneering use of 18th century performing style; Massenet's Werther; Donizetti's Mary Stuart with Baker; and Sullivan's Patience. The company took the production of the last to the Vienna Festival in 1975, along with Britten's Gloriana. Sir Charles Groves succeeded Mackerras as musical director from 1978 to 1979, but Groves was unwell and unhappy during his brief tenure. Starting in 1979, Mark Elder succeeded Groves in the post, and described Groves "immensely encouraging and supportive".A long-standing concern of Arlen and then Harewood was the need to change the company's name to reflect the fact that it was no longer based at Sadler's Wells theatre. Byam Shaw commented "The one major setback the Sadler's Wells Opera Company suffered from its transplant was that unheeding taxi drivers kept on taking their patrons up to Rosebery Avenue".Harewood...  answer the following question:  What was the last name of the person who was the managing director of Sadler's Wells Opera on 21 August 1968?

input: Please answer the following: Given the following context:  The general impact of Olney Hymns was immediate and it became a widely popular tool for evangelicals in Britain for many years. Scholars appreciated Cowper's poetry somewhat more than Newton's plaintive and plain language driven from his forceful personality. The most prevalent themes in the verses written by Newton in Olney Hymns are faith in salvation, wonder at God's grace, his love for Jesus, and his cheerful exclamations of the joy he found in his faith. As a reflection of Newton's connection to his parishioners, he wrote many of the hymns in first person, admitting his own experience with sin. Bruce Hindmarsh in Sing Them Over Again To Me: Hymns and Hymnbooks in America considers "Amazing Grace" an excellent example of Newton's testimonial style afforded by the use of this perspective. Several of Newton's hymns were recognised as great work ("Amazing Grace" was not among them) while others seem to have been included to fill in when Cowper was unable to write. Jonathan Aitken calls Newton, specifically referring to "Amazing Grace", an "unashamedly middlebrow lyricist writing for a lowbrow congregation", noting that only twenty-one of the nearly 150 words used in all six verses have more than one syllable.William Phipps in the Anglican Theological Review and author James Basker have interpreted the first stanza of "Amazing Grace" as evidence of Newton's realisation that his participation in the slave trade was his wretchedness, perhaps representing a wider common understanding of Newton's motivations. Newton joined forces with a young man named William Wilberforce, the British Member of Parliament who led the Parliamentarian campaign to abolish the slave trade in the British Empire, culminating in the Slave Trade Act 1807. However, Newton became an ardent and outspoken abolitionist after he left Olney in the 1780s; he never connected the construction of the hymn that became "Amazing Grace" to anti-slavery sentiments. The lyrics in Olney Hymns were arranged by their association to the Biblical verses that...  answer the following question:  What is the name of the act created in 1807 by the man who wrote the Olney Hymns and the parliament member?
++++++++++
output: Slave Trade Act 1807


input: Please answer the following: Given the following context:  In September 2010, Mikael Åkerfeldt stated that he was writing for a new Opeth album. The band announced on their website that they would start recording their tenth album on January 31, 2011, at the Atlantis/Metronome studios in Stockholm, once again with Jens Bogren (engineering) and Steven Wilson from Porcupine Tree as co-producer.Shortly after mixing was complete on the new album in April 2011, Opeth announced that Per Wiberg was relieved of his duties in the band. In the press statement, Mikael Åkerfeldt explained the decision, saying, "Mendez, Axe and Fredrik and I came to the decision that we should find a replacement for Per right after the recordings of the new album, and this came as no surprise to Per. He had, in turn, been thinking about leaving, so you could say it was a mutual decision. There's no bad blood, just a relationship that came to an end, and that's that."Opeth's tenth album, Heritage, was released on September 14, 2011, to generally favorable reviews. The album sold 19,000 copies in the United States in its first week of release and debuted at number 19 on the Billboard 200 chart. Heritage debuted at number four in the band's native country of Sweden.Heritage became the second Opeth album to not feature any death growls and had a much more progressive style than previous albums from the band, something that Åkerfeldt had been wanting to do for some time.The first two songs Åkerfeldt wrote for Heritage were in the style of Watershed. After hearing the songs for the first time, Martín Méndez told Åkerfeldt that he would be disappointed if the album continued in that direction. Relieved that Méndez was not interested in doing another conventional Opeth album, Åkerfeldt scrapped the two songs and started the writing process over in a different style. In the press release for Heritage, Mikael Åkerfeldt revealed that he felt as though he had been building to write the album since he was 19 years old. In a review for Allmusic, Thom Jurek called Heritage the band's most adventurous album,...  answer the following question:  What is the first name of the person who wanted a much more progressive style than previous albums from the band for some time?
