Question: When did Simon and Garfunkel play in the place where The Gates artwork was sited?

full_context: Document 1: From Bauhaus to Our House: After "The Painted Word", Wolfe published a collection of his essays, "Mauve Gloves & Madmen, Clutter & Vine" (1976), and his history of the earliest years of the space program, "The Right Stuff" (1979). Undeterred by the hostile critical response to "The Painted Word", and perhaps even encouraged by the stir the book made, Wolfe set about writing a critique of modern architecture. "From Bauhaus to Our House" was excerpted in "Harper's Magazine" and published by Wolfe's long-time publisher Farrar, Straus & Giroux in 1981.
Document 2: The Gates: The books and other memorabilia distributed by Christo and Jeanne-Claude refer to the project as "The Gates, Central Park, New York, 1979–2005" in reference to the time that passed from the artists' initial proposal until they were able to go ahead with it.
Document 3: 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 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: 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 6: The New Colossus: ``The New Colossus ''was the first entry read at the exhibit's opening on November 2, 1883, and remained associated with the exhibit through a published catalog until the exhibit closed after the pedestal was fully funded in August 1885, but was forgotten and played no role at the opening of the statue in 1886. It was, however, published in Joseph Pulitzer's New York World as well as The New York Times during this time period. In 1901, Lazarus's friend Georgina Schuyler began an effort to memorialize Lazarus and her poem, which succeeded in 1903 when a plaque bearing the text of the poem was put on the inner wall of the pedestal of the Statue of Liberty.
Document 7: 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 10: One & Other: One & Other was a public art project by Antony Gormley, in which 2,400 members of the public occupied the usually vacant fourth plinth in Trafalgar Square, London, for an hour each for 100 days.
