The group's sixth album, "Fancy Free", released early in 1981, contained the Dallas Frazier-penned song "Elvira". This remains the group's most widely known song, and "Fancy Free" is their best-selling album. "Elvira" had been recorded by other artists, including Frazier himself in the late 1960s and The First Edition in 1970, but the Oak Ridge Boys were the first to have a hit with it. Their version of the song was a number-one country hit, and in July 1981 reached No. 5 on the pop charts.
