With their heyday in the '60s and '70s, Ashford and Simpson wrote hit after hit for the likes of Diana Ross, Gladys Knight, Smokey Robinson, Aretha Franklin, Chaka Khan, Ray Charles and other Motown superstars.

As a singing group themselves, Ashford and Simpson recorded such smashes at "Don't Cost You Nothin'" and 1984's "Solid." They continued recording and touring up until very recently.
