The Sound Of Philadelphia” by MFSB (Mother, Father, Sister, Brother) featuring vocals by the group The Three Degrees was written by Philly Soul legends Kenneth Gamble and Leon Huff as the theme song for the television show Soul Train.  The song reached #1 on both the Billboard Hot 100 and the R&B chart in 1974.  Although the song was re-recorded in different versions over the different eras of black music (’80s R&B, New Jack Swing, Hip-Hop, Neo-Soul) since 1974, “The Sound Of Philadelphia” remained the show’s theme song until the final episode in 2006.
