Old Friends is a CD box set of Simon and Garfunkel songs, released in 1997. The three-disc anthology collects most of the duo's best-known works, and also includes previously unreleased outtakes. Some of these outtakes subsequently appeared on both the reissues of Simon and Garfunkel's five studio albums as well as the later boxed set The Columbia Studio Recordings (1964-1970).
The Sound of Silence - The song's origin and basis remains unclear, with multiple answers coming forward over the years. Many believe that the song commented on the John F. Kennedy assassination, as the song was released three months after the assassination. Simon stated in interviews that the song was written in his bathroom, where he turned off the lights to better concentrate.
