 The following year, the Butlers were invited to join the Grand Ole Opry, and the exposure provided by the show helped them push "Don't Let Me Cross Over" to number one.Their first single as a duo spent almost three months at the top of the country music charts and they remained one of country music's most popular duos for the next two decades.Later chart records included "I Wouldn't Change You If I Could", "Too Late To Try Again", "Loving Arms" and "I'm Hanging Up The Phone".
