The Isley Brothers - Shout

The Isley Brothers are a highly influential, successful and long-running American music group consisting of different line-ups of six brothers, and a brother-in-law, Chris Jasper. The founding members were O'Kelly Isley, Jr., Rudolph Isley, Ronald Isley and Vernon Isley. Starting their careers in the gospel performing circuit in the early 1950s, they eventually crossed over to secular music first finding modest success in doo-wop until the release of their first million-selling hit, «Shout», in 1959. from Wikipedia
