Simon and Garfunkel’s “Sound Of Silence” is one of the best songs of all time and was inspired by Sanford “Sandy” Greenberg, Art Garfunkel roomate and best friend who lost his vision. Sanford released a moving new memoir named “Hello Darkness, My Old Friend: How Daring Dreams and Unyielding Friendship Turned One Man’s Blindness into an Extraordinary Vision for Life”.
