The Four Step Brothers

Bio taken from Wiki: "The Four Step Brothers were an African-American dance group. The group started out as a trio in 1925, with the original members, Maceo Anderson, Al Williams and Red Walker. Although their original name was the Step Brothers, because that was also the name of another famous young tap dancing quartet, they subsequently changed their name to "The Three Step Brothers." In 1927, after accepting a new member, Sherman Robertson, they became The Four Step Brothers. Dubbed "The Eight Feet of Rhythm," the group soon traveled with Duke Ellington. While starring with the "Brothers," Anderson also appeared at the Hoofer Club and worked part-time as a newsboy."
