The songwriting/production duo of Ashford and Simpson met in a New York Baptist church where Valerie Simpson played piano. Their gospel music background can be felt in many of their songs, including the hits they wrote for the Motown singing duo Marvin Gaye and Tammi Terrell. A grand example would be "You're All I Need to Get By." It begins quietly as both the singers and the songwriters/producers harmonize the title over a repeating bass note pattern played by James Jamerson. The passions steadily rise with both Gaye's and Terrell's vocals moving the temperature mark higher. The tenderness heard in their vocals fueled rumors that the singers were lovers. "You're All I Need to Get By" held the number one R&B spot for five weeks, while going to number seven pop in the summer of 1968.
