Question: When did Simon and Garfunkel play in the place where King Jagiello Monument is located?

full_context: Document 1: The Concert for Bangladesh: The Concert for Bangladesh (or Bangla Desh, as the country's name was originally spelt) was a pair of benefit concerts organised by former Beatles lead guitarist George Harrison and Indian sitar player Ravi Shankar. The shows were held at 2:30 and 8:00pm on Sunday, 1 August 1971, at Madison Square Garden in New York City, to raise international awareness of, and fund relief for refugees from East Pakistan, following the Bangladesh Liberation War-related genocide. The concerts were followed by a bestselling live album, a boxed three-record set, and Apple Films' concert documentary, which opened in cinemas in the spring of 1972.
Document 2: Battle of Legnica: The Battle of Legnica (), also known as the Battle of Liegnitz () or Battle of Wahlstatt (), was a battle between the Mongol Empire and the combined defending forces of European fighters that took place at Legnickie Pole ("Wahlstatt") near the city of Legnica in the Duchy of Silesia on 9 April 1241.
Document 3: Simon & Garfunkel: Simon & Garfunkel were an American folk rock duo consisting of singer - songwriter Paul Simon and singer Art Garfunkel. They were one of the best - selling music groups of the 1960s and became counterculture icons of the decade's social revolution, alongside artists such as the Beatles, the Beach Boys, and Bob Dylan. Their biggest hits -- including ``The Sound of Silence ''(1964),`` Mrs. Robinson'' (1968), ``The Boxer ''(1969), and`` Bridge over Troubled Water'' (1970) -- reached number one on singles charts worldwide.
Document 4: Simon & Garfunkel: Despite this, the duo have not staged a full - scale tour or performed shows since 2010. Garfunkel confirmed to Rolling Stone in 2014 that he believes they will tour in the future, although Simon had been too ``busy ''in recent years.`` I know that audiences all over the world like Simon and Garfunkel. I'm with them. But I do n't think Paul Simon's with them,'' he remarked. In a 2016 interview with NPR's David Greene, when asked about the possibility of reuniting, Simon stated; ``Well, I do n't think most people do (constantly want Simon to relive the olden days). The fact is, is, like, we did do two big reunions, and we're done. There's nothing really much to say. You know, the music essentially stopped in 1970. And, you know, I mean, quite honestly, we do n't get along. So it's not like it's fun. If it was fun, I'd say, OK, sometimes we'll go out and sing old songs in harmony. That's cool. But when it's not fun, you know, and you're going to be in a tense situation, well, then I have a lot of musical areas that I like to play in. So that'll never happen again. That's that. ''
Document 5: Battle of Grunwald: The Battle of Grunwald, First Battle of Tannenberg or Battle of Žalgiris was fought on 15 July 1410 during the Polish–Lithuanian–Teutonic War. The alliance of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania, led respectively by King Władysław II Jagiełło (Jogaila) and Grand Duke Vytautas, decisively defeated the German–Prussian Teutonic Knights, led by Grand Master Ulrich von Jungingen. Most of the Teutonic Knights' leadership were killed or taken prisoner. Although defeated, the Teutonic Knights withstood the siege of their fortress in Marienburg (Malbork) and suffered minimal territorial losses at the Peace of Thorn (1411) (Toruń), with other territorial disputes continuing until the Peace of Melno in 1422. The knights, however, would never recover their former power, and the financial burden of war reparations caused internal conflicts and an economic downturn in the lands under their control. The battle shifted the balance of power in Central and Eastern Europe and marked the rise of the Polish–Lithuanian union as the dominant political and military force in the region.
Document 6: The Concert in Central Park: The Concert in Central Park, released in February 1982 on Warner Bros. Records, is the first live album by American folk rock duo Simon & Garfunkel. It was recorded in September 1981 at a free benefit concert in Central Park, New York City, where the pair performed in front of more than 500,000 people. Proceeds went toward the redevelopment and maintenance of the park, which had deteriorated due to lack of municipal funding. The concert and album marked the start of a short - lived reunion for Paul Simon and Art Garfunkel. The concept of a benefit concert in Central Park had been proposed by Parks Commissioner Gordon Davis and promoter Ron Delsener. Television channel HBO agreed to carry the concert, and worked with Delsener to decide on Simon and Garfunkel as the appropriate act for this event. Besides hit songs from their years as a duo, their set - list included material from their solo careers, and covers. The show consisted of 21 songs, though two were not used in the live album. Among the songs performed were the classics ``The Sound of Silence '',`` Mrs. Robinson'', and ``The Boxer ''; the event concluded with a reprise of Simon's song,`` Late in the Evening''. Ongoing personal tensions between the duo led them to decide against a permanent reunion, despite the success of the concert and a subsequent world tour.
Document 7: Warsaw: There are also many places commemorating the heroic history of Warsaw. Pawiak, an infamous German Gestapo prison now occupied by a Mausoleum of Memory of Martyrdom and the museum, is only the beginning of a walk in the traces of Heroic City. The Warsaw Citadel, an impressive 19th-century fortification built after the defeat of the November Uprising, was a place of martyr for the Poles. Another important monument, the statue of Little Insurgent located at the ramparts of the Old Town, commemorates the children who served as messengers and frontline troops in the Warsaw Uprising, while the impressive Warsaw Uprising Monument by Wincenty Kućma was erected in memory of the largest insurrection of World War II.
Document 8: Live at Shea Stadium: The Concert: Live at Shea Stadium: The Concert is a CD and DVD music compilation of songs performed by American singer / songwriter Billy Joel during two concerts at Shea Stadium in New York City on July 16 and 18 of 2008. It was released on March 8, 2011. The film was produced by Jon Small, Joel's former bandmate in the 1960s groups The Hassles and Attila.
Document 9: The Sound of Silence: Released in October 1964, the album was a commercial failure and led to the duo breaking apart, with Paul Simon returning to England and Art Garfunkel to his studies at Columbia University. In spring 1965, the song began to attract airplay at radio stations in Boston, Massachusetts, and throughout Florida. The growing airplay led Tom Wilson, the song's producer, to remix the track, overdubbing electric instrumentation. Simon & Garfunkel were not informed of the song's remix until after its release. The single was released in September 1965.
Document 10: King Jagiello Monument: The King Jagiełło Monument is an equestrian monument of Władysław II Jagiełło, King of Poland and Grand Duke of Lithuania, located in Central Park, New York City. The monument commemorates the Battle of Grunwald, a decisive defeat of the Teutonic Order in 1410. Originally made for the Polish 1939 New York World's Fair pavilion, the monument was permanently installed in Central Park in 1945. Raised on its grand plinth it is one of the most prominently-sited and impressive of twenty-nine sculptures located in the park.
Document 11: Union of Krewo: In a strict sense, the Union of Krewo or Act of Krėva (also spelled Union of Krevo, Act of Kreva; ; ) was a set of prenuptial promises made in the Kreva Castle on 14 August 1385 by Jogaila, Grand Duke of Lithuania, in exchange for marriage to the underage reigning Queen Jadwiga of Poland. The act was very limited in scope and in the historiography the term "Union of Krewo" often refers not only to the particular document but to the events of 1385–1386 as a whole. After the negotiations in 1385, Jogaila converted to Christianity, married Jadwiga, and was crowned King of Poland in 1386. The union was a decisive moment in the histories of Poland and Lithuania; it marked a beginning of the four centuries of shared history between the two nations. By 1569 the Polish–Lithuanian union grew into a new state, the Polish–Lithuanian Commonwealth, and lasted until the Third Partition in 1795.
Document 12: East Prussia: Upon the invitation of Duke Konrad I of Masovia, the Teutonic Knights took possession of Prussia in the 13th century and created a monastic state to administer the conquered Old Prussians. Local Old-Prussian (north) and Polish (south) toponyms were gradually Germanised. The Knights' expansionist policies, including occupation of Polish Pomerania with Gdańsk/Danzig and western Lithuania, brought them into conflict with the Kingdom of Poland and embroiled them in several wars, culminating in the Polish-Lithuanian-Teutonic War, whereby the united armies of Poland and Lithuania, defeated the Teutonic Order at the Battle of Grunwald (Tannenberg) in 1410. Its defeat was formalised in the Second Treaty of Thorn in 1466 ending the Thirteen Years' War, and leaving the former Polish region Pomerania/Pomerelia under Polish control. Together with Warmia it formed the province of Royal Prussia. Eastern Prussia remained under the Knights, but as a fief of Poland. 1466 and 1525 arrangements by kings of Poland were not verified by the Holy Roman Empire as well as the previous gains of the Teutonic Knights were not verified.
Document 13: Live from New York City, 1967: Live from New York City, 1967 is the second live album by Simon & Garfunkel, recorded at Philharmonic Hall at Lincoln Center in New York City, on 22 January 1967. The album was released on the Columbia Legacy CK 61513 label on 16 July 2002.
Document 14: Grunwald Swords: The Grunwald Swords (, ) were a gift presented by Ulrich von Jungingen, the Grand Master of the Order of Teutonic Knights, to King Władysław II Jagiełło of Poland and Grand Duke Vytautas of Lithuania on 15 July 1410, just before the Battle of Grunwald (Tannenberg). The gift, a pair of simple bare swords, was a formal invitation to the battle. After the Polish-Lithuanian victory, both swords were taken as a war trophy by King Władysław II to Kraków, Poland's capital at the time, and placed in the treasury of the Royal Wawel Castle.
Document 15: Ulrich von Jungingen: Ulrich von Jungingen (c.a. 1360 – 15 July 1410) was the 26th Grand Master of the Teutonic Knights, serving from 1407 to 1410. His policy of confrontation with the Grand Duchy of Lithuania and the Kingdom of Poland would spark the Polish–Lithuanian–Teutonic War and lead to disaster for his Order, and his own death, at the Battle of Grunwald.
