found: Wikipedia website, viewed July 9, 2024:Oak Ridge Boys page (the Oak Ridge Boys are an American country and gospel vocal quartet originating in Oak Ridge, Tennessee; the group was founded in 1943 as the Oak Ridge Quartet; they became popular in Southern gospel during the 1950s; their name was changed to the Oak Ridge Boys in the early 1960s, and they remained a gospel group until the mid-1970s, when they changed their image and concentrated on country music; the lineup that 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 vocals), William Lee Golden (baritone), Richard Sterban (bass), and, until his 2024 death, Joe Bonsall (tenor). Golden and Allen joined the group in the mid-1960s, and Sterban and Bonsall joined in the early 1970s. Golden was removed from the group in 1987 and replaced by Steve Sanders until 1995, when he left and Golden rejoined; in late 2023, Bonsall retired from touring, with Ben James filling in on the road; in 2024, Bonsall died from complications of ALS; the group was inducted into the Country Music Hall of Fame in 2015.) - https://en.wikipedia.org/wiki/The_Oak_Ridge_Boys
