The Cowsills are an American singing group from Newport, Rhode Island, six siblings noted for performing professionally and singing harmonies at an early age, later with their mother.
The band was formed in the spring of 1965 by brothers Bill, Bob, and Barry Cowsill; with their brother John joining shortly thereafter. Originally Bill and Bob played guitar and Barry played the drums. When John learned to play drums and joined the band, Barry began playing bass. After their initial success, the brothers were joined by their siblings Susan and Paul along with their mother, Barbara. A seventh sibling, Bob’s twin brother Richard, was never part of the band during its heyday, although he occasionally appeared with them in later years.
