 The first track of the box set is the Buddy Holly-produced "Jole Blon," released in 1958, while the last is "I Do Believe," a song produced by Don Was that was included on The Highwaymen's 1995 release, "The Road Goes on Forever".The other material on the box set covers Jennings' career chronologically, with songs ranging from his years on RCA's roster to later compositions from his short-lived stay at Epic Records; it ignores, however, the tracks from Jennings albums released on independent labels.The majority of the singer's charting singles are included in the package, as are collaborations such as "Mamas Don't Let Your Babies Grow Up to Be Cowboys" with Willie Nelson and "Highwayman" with The Highwaymen.
