The Oak Ridge Boys signed with Columbia IN 1975 but found the initial transition a rough one: They split their time between country and gospel, and without a strong identity their sales dropped. The resulting financial problems nearly forced them to disband, and a discouraged Columbia gave up on them after the 1976 single "Family Reunion" barely charted, even though labelmate Paul Simon had tapped them to sing backup on his hit "Slip Slidin' Away." Fortunately, they got another chance with MCA and scored a breakout Top Five hit in 1977 with "Y'all Come Back Saloon," the title song from their label debut. The follow-up, "You're the One," reached number two, and their next album, 1978's Room Service, gave them their first number one hit in "I'll Be True to You" as well as two more Top Five hits in "Cryin' Again" and "Come On In."

Thus established as country hitmakers, the Oak Ridge Boys embarked on a run of chart success that would last through the '80s.

They hit number one again in 1980 with "Trying to Love Two Women," but it was the following year that would make them a genuine phenomenon. Their recording of "Elvira," an obscure, doo wop-style novelty song from the '60s, became a major, Grammy-winning crossover smash. Not only did it hit number one on the country charts, but its infectious "oom-pop-a-mow-mow" bass vocal hook boosted it into the Top Five on the pop charts. Its accompanying album, Fancy Free, became their first to top the country charts, not to mention their biggest seller ever. The title cut of their chart-topping 1982 follow-up, Bobbie Sue, also went number one country and nearly made the pop Top Ten as well. American Made's title track also topped the charts in 1983, as did its follow-up, "Love Song." In early 1984 Deliver became their third number one country album, and they landed two more number one singles that year with "Everyday" and "I Guess It Never Hurts to Hurt Sometimes." 1985 brought three number ones: "Little Things," "Make My Life With You," and "Touch a Hand, Make a Friend."

The Oak Ridge Boys' sales began to slow a bit in the latter half of the '80s, but they still produced big hits with regularity. They hit number one in 1987 ("It Takes a Little Rain," "This Crazy Love"), 1988 ("Gonna Take a Lot of River"), and 1990 ("No Matter How High"), giving them a total of 16 career country chart-toppers (and 29 Top Ten hits).

 In 1991, the Oak Ridge Boys parted ways with MCA and signed with RCA, but after just two albums, it was apparent that their commercial prime had passed, and the relationship ended. The group returned to traditional-style country gospel on occasion during the '90s and continued to tour. Meanwhile, Sanders' marital problems worsened, causing him to leave the group in late 1995; Golden and the other members resolved their differences, and he returned at their New Year's Eve show that year; they still performed often, notably in Branson, MO. Sadly, Sanders shot and killed himself in 1998. Fox, who moved on to run the group's publishing arm and later became a high-ranking music executive, passed away in April 2003.
