Paul Simon Performs 'The Sound of Silence' at 9/11 Memorial

At the 9/11 Memorial Ceremony Sunday morning folk singer Paul Simon gave a gripping performance of his song, "The Sound of Silence":

Simon had reportedly intended on performing "Bridge Over Troubled Water." It is unclear why Simon decided to change songs, but his choice was well received nonetheless.

Simon was the first musical guest on Saturday Night Live following the September 11, 2001 attacks. In 2001, Simon performed "The Boxer" on stage with Mayor Rudy Giuliani, and members of the NYPD and FDNY looking on.

Simon is a native of Queens.
