Johnny Rivers (born John Henry Ramistella, 7 November 1942, in New York) is an American rock and roll singer, songwriter, guitarist, and record producer. He was versatile enough to do folk songs, blues, and revivals of old-time rock 'n' roll songs and some original material. Rivers's greatest success came in the mid and late 1960s with a string of hit songs (including "Seventh Son", "Poor Side of Town", "Summer Rain", and "Secret Agent Man"), but he has continued to record and perform to the present.
