Paul Simon was on hand at the ceremony marking the anniversary of the September 11 World Trade Center attacks in New York. Simon, wearing a 9/11 Memorial baseball cap, sang the Simon & Garfunkel classic 'The Sound of Silence' to heartbreaking effect for the crowd of family, friends and colleagues mourning those who lost their lives 10 years ago.
