Garfunkel's final studio album, was released in January 1970 and charted in over 11 countries, topping the charts in 10, including the Billboard Top LP's chart in the US and the UK Albums Chart. It was the best-selling album in 1970, 1971 and 1972 and was at that time the best-selling album of all time. It was also CBS Records' best-selling album before the release of Michael Jackson's Thriller in 1982. The album topped the Billboard charts for 10 weeks and stayed in the charts for 85 weeks. In the United Kingdom, the album topped the charts for 35 weeks, and spent 285 weeks in the top 100, from 1970 to 1975. It has since sold over 25 million copies worldwide. "Bridge over Troubled Water", the lead single, reached number one in five countries and became the duo's biggest seller. The song has been covered by over 50 artists, including Elvis Presley, Johnny Cash, Aretha Franklin, Jim Nabors, Charlotte Church, Maynard Ferguson, Willie Nelson, Roy Orbison, Michael W. Smith, Josh Groban, and The Mormon Tabernacle Choir. "Cecilia", the follow-up, reached number four in the US, and "El Condor Pasa" hit number 18. A brief British tour followed the album release, and the duo's last concert as Simon & Garfunkel took place at Forest Hills Stadium. In 1971, the album won six awards at the 13th Annual Grammy Awards, including Album of the Year. 1971–1990: Breakup, rifts, and reunions The recording of Bridge over Troubled Water was difficult, and Simon and Garfunkel's relationship had deteriorated. "At that point, I just wanted out," Simon later said. At the urging of his wife, Peggy Harper, Simon called Davis to confirm the duo's breakup. For the next several years, they spoke only two or three times a year. In the 1970s, the duo reunited several times. Their first reunion was Together for McGovern, a benefit concert for presidential candidate George McGovern at New York's Madison Square Garden in June 1972. In 1975, they reconciled when they visited a recording session with John Lennon and Harry Nilsson. For the rest of the year, they attempted to make the reunion work, but their collaboration only yielded one song, "My Little Town", that was featured on Simon's Still Crazy After All These Years and Garfunkel's Breakaway, both released in 1975. That year, Garfunkel joined Simon for a medley of three songs on Saturday Night Live, guest-hosted by
