Bristol was professionally and personally part of Motown, as he married Iris Gordy, and was also Harvey Fuqua's writing and production partner for several years. They co-produced Junior Walker & the All-Stars' remake of "How Sweet It Is" in 1966, then co-wrote and produced "What Does It Take." Bristol wrote and/or produced songs for Diana Ross, Marvin Gaye and Tammi Terrell, Smokey Robinson, David Ruffin, Edwin Starr, Michael Jackson, Gladys Knight & the Pips, Martha Reeves, Jimmy Ruffin, the Spinners, the Four Tops, and Stevie Wonder. "Ain't No Mountain High Enough," "25 Miles," "Help Me Make It Through The Night," "I Don't Want to Do Wrong," and "Yester-Me, Yester-You, Yesterday" were some of the songs featuring Bristol's input. He signed with MGM as a solo artist in 1974. His first single, "Hang on In There Baby," was his biggest; it was number two R&B and number-eight pop that year. Bristol enjoyed two more sizable hits for MGM, "You and I" and "Leave My World" in 1974 and 1975.
He moved to Atlantic in 1976, and scored his last hit with "Do It to My Mind," a number-five R&B record. The Osmonds also had a number one record in England with Bristol's "Love Me for a Reason." Bristol remade "Hang on In There Baby" as a duet with Alton McClain for Polydor in 1980, and did another duet with Amii Stewart titled "My Guy/My Girl" for Handshake. He recorded for England's Motorcity label, and scored a British hit with "Man Up in the Sky" in 1989. His last entry was "Come to Me" for Whichway in 1991. Bristol was also productive as a writer and producer in the '70s and '80s; Tavares, Buddy Miles, Tamiko Jones, Real Thing, O.C. Smith, and Margie Joseph recorded his compositions in the '70s, and Bristol produced a Four Tops remake of "I'm Ready for Love" in 1985, briefly returning to Motown. The veteran songwriter and producer passed away in March of 2004 at the age of 65. ~ Ron Wynn, Rovi
