Simon and Garfunkel's Greatest Hits

From Wikipedia:

Simon and Garfunkel's Greatest Hits is the first greatest hits album by Simon & Garfunkel, released on June 14, 1972, two years after Simon & Garfunkel disbanded.[1] In 2003, it was ranked No. 293 on Rolling Stone's list of the 500 greatest albums of all time.

The album was a mix of original studio recordings and four previously unreleased live recordings. The album's minimalist packaging does not specifically date the latter;[2] however, the live versions of "For Emily, Whenever I May Find Her" and "Kathy's Song" included on Greatest Hits were also included on the 2008 album Live 1969. The liner notes to Live 1969 state that these two songs were both recorded at a November 1969 concert in St. Louis, Missouri. According to the liner notes from Collected Works, however, the version of "Kathy's Song" was taken from a 1968 concert in Vermont
