The lineup which produced their most well-known country and crossover hits (such as "Elvira" (1981), "Bobbie Sue" (1982), and "American Made" (1983) consists of Duane Allen (lead), Joe Bonsall (tenor), William Lee Golden (baritone), and Richard Sterban (bass). Golden and Allen joined the group in the mid-1960s, and Sterban and Bonsall joined in the early 1970s. Aside from an eight-year gap (1987–95) when Golden left the group and was replaced, this lineup has been together since 1973 and continues to tour and record.
