Paul Simon Gives Poignant Performance of ‘The Sound of Silence’ at Ground Zero [VIDEO]

During Sunday’s ceremony marking the 10th anniversary of the terrorist attacks on the World Trade Center, Paul Simon gave a haunting acoustical performance of ‘The Sound of Silence’ while some onlookers wept.

The song that first propelled Simon and his former musical partner Art Garfunkel into the national spotlight in 1965 was originally written by Simon in reaction to the assassination of President John F. Kennedy, but its lyrics took on a new poignancy during the Ground Zero memorial.
