Sister Sledge is an American musical group from Philadelphia, Pennsylvania, formed in 1972 and consisting of four singers, all of whom are sisters: Kim Sledge (born 21 August 1957), Debbie Sledge (born 9 July 1954), Joni Sledge (born 13 September 1956), and Kathy Sledge (born 6 January 1959). Chart history Born and raised in Philadelphia, Sister Sledge, discovered by Charles Simmons of West Philadelphia, took the world by storm with their singing style, which was developed from singing in local Philadelphia churches like the Second Macedonia Baptist Church. First entering the UK Singles Chart in 1975 with "Mama Never Told Me" and the US Singles Chart with "Love Don't You Go Through No Changes On Me," in 1975, their career went into decline before it revived under the magisterial production skills of Nile Rodgers and Bernard Edwards of Chic.
