Simon & Garfunkel were an American folk rock duo consisting of singer-songwriter Paul Simon and singer Art Garfunkel. They were one of the bestselling music groups of the 1960s and became counterculture icons of the decade's social revolution, alongside artists such as the Beatles, the Beach Boys, and Bob Dylan. Their biggest hits-including "The Sound of Silence" (1964), "Mrs. Robinson" (1968), "The Boxer" (1969), and "Bridge over Troubled Water" (1970)-reached number one on singles charts worldwide.
