The McCoys were an American rock group formed in Union City, Indiana, in 1962. The band is best known for its 1965 hit "Hang on Sloopy," which topped the U.S. charts and became a garage rock classic. Notable band members include Rick Derringer, who later enjoyed a successful solo career. The McCoys' style was characterized by a blend of rock, pop, and blues, and their youthful, energetic sound exemplified the teen-beat aesthetic of the mid-1960s.
