As we all know "Ain't No Mountain High Enough" was written by Ashford and Simpson. It was first recorded by Tammi Terrell with vocals by Marvin Gaye added after the fact. But this version was produced by Bristol & Fuqua. Later, Ashford & Simpson produced a totally new version of the song with Diana Ross. Does anyone know if Ashford & Simpson were ever given a shot a producing the original? Did they have any production input with Bristol & Fuqua? I wonder how they would have done it. Do you think it would have wound up sounding more like Diana's take? Thanks.
