sentences:  Although "Country Heart" contained several hits Jones had scored with Musicor, it is not actually a greatest hits collection.It includes a rerecording of Jones's first number one country hit "White Lightnin'" as well as a remake of his hit duet "We Must Have Been Out Of Our Minds" with Melba Montgomery from 1963.Curiously, the album also features an instrumental version of "The Race Is On", which had gone to number three for Jones in 1964 when he was still with United Artists.
