"Ain't No Mountain High Enough" is a song written by Nickolas Ashford & Valerie Simpson and in 1970 remade by Diana Ross. The remake was similar to gospel with elements of classical music strings, spoken word passages from Ross, with The Andantes, Jimmy Beavers, Jo Armstead, Ashford & Simpson, and Brenda Evans and Billie Calvin of The Undisputed Truth as backing singers, giving the song a soul and gospel vocal element.
