Ashford and Simpson met at Harlem's White Rock Baptist Church in 1963.

Another of the trio's songs "Let's Go Get Stoned" gave Ray Charles a number one U.S. R&B hit in 1966. That same year Ashford & Simpson joined Motown where their best-known songs included "Ain't No Mountain High Enough", "You're All I Need To Get By", "Ain't Nothing Like the Real Thing", and "Reach Out and Touch (Somebody's Hand)".

The duo was inducted into the Songwriters Hall of Fame in 2002.
