The Unlimited Four were a soul vocal group who recorded several 45s for Toledo's Chanson label. A couple of the 45s were local hits in the Detroit/Toledo area.
The group included Joe Butts (lead vocals), Bobby Davis, Willie Vaughn, and Ronnie Foster. Charles Nelson Jr. replaced Ronnie Foster.
The records were recorded in Detroit, and backed on most or all recordings by d'Kalenders, who were also from Detroit.
Joe Butts was the lead singer in the Magnificent Opinions in the 1980s.
