The Three D's was an American folk music trio known for their unique blend of traditional and contemporary songs. Comprising members Dick Davis, Duane Hiatt, and Denis Sorenson, the group achieved prominence in the 1960s and 70s, largely within the Latter-day Saint music scene. The Three D's were particularly noted for their tight harmonies and clean-cut, collegiate image. Their song "Pass It On" remains an influential work within their genre, capturing their signature sound of uplifting, folk-infused melodies.
