The Swan Silvertones are an American gospel music group that first achieved popularity in the 1940s and 1950s under the leadership of Claude Jeter. Jeter formed the group in 1938 as the "Four Harmony Kings" while he working as a coal miner in West Virginia. After moving to Knoxville, Tennessee and obtaining their own radio show, the group changed its name to the "Silvertone Singers" in order to avoid confusion with another ensemble known as the "Four Kings of Harmony." They added the name Swan shortly thereafter, since Swan Bakeries sponsored their show. Their wide exposure through radio brought them a contract with King Records.

At this early stage, the Silvertones already embodied an amalgam of two styles: the close barbershop harmonies that they had featured when starting out in West Virginia, and virtuoso leads supplied by Jeter and Solomon Womack. The group later lost Womack, but added Paul Owens in 1952 and Louis Johnson in 1955. The three singers with their sharply contrasting styles — Jeter a tenor who could sing falsetto without losing his lyric control, Owens a crooner, and Johnson a hard shouter — played off each other to great effect in songs such as "Mary Don't You Weep."
