The O'Jays are an American R&B group from Canton, Ohio, formed in summer 1958 and originally consisting of Eddie Levert, Walter Lee Williams, William Powell, Bobby Massey, and Bill Isles. The O'Jays made their first chart appearance with the minor hit "Lonely Drifter" in 1963, but reached their greatest level of success once the producers Gamble & Huff signed them to their Philadelphia International label in 1971. With Gamble & Huff, the O'Jays emerged at the forefront of Philadelphia soul with "Back Stabbers" (1972), and topped the US Billboard Hot 100 the following year with "Love Train". From Wikipedia →
