Hits: Greatest and Others was a 1973 compilation Vanguard put together at the end of Joan Baez' association with their label.
 In addition to her hit cover of The Band's "The Night They Drove Old Dixie Down", songs by the Beatles and Kris Kristofferson were also included.
 Unlike previous compilations, this one skipped over most of Baez' earlier traditional material almost entirely, in favor of her more recent singer-songwriter material and covers.
Rainbow is the 70th album by American country singer Johnny Cash, his last for Columbia Records, released in 1985 (see 1985 in country music).
 "I'm Leaving Now", which appeared fifteen years later as a track on Cash's "", was released as a single rather unsuccessfully, but the album's signature song is a cover of Kris Kristofferson's "Here Comes That Rainbow Again", which also appeared on Cash's 1995 collaboration with Kristofferson, Willie Nelson and Waylon Jennings - known as The Highwaymen - entitled "The Road Goes on Forever", though it was sung solo by Kristofferson on the latter.
 Also included is a cover of Creedence Clearwater Revival's "Have You Ever Seen the Rain?
," from "Pendulum".
 The album also includes the song "Love Me Like You Used To," which was later recorded by fellow country singer Tanya Tucker, and became a country hit for her.
 Following the release of this album and a duet album with Jennings in 1986, Cash moved to Mercury Records as a result of Columbia's fading interest in his music, though he later returned to Columbia for the second Highwaymen album.
Repossessed is an album by Kris Kristofferson, released on Mercury Records in 1986 (see 1986 in music).
 It was Kristofferson's first full-length solo album since 1981's "To the Bone", although the singer did collaborate with other artists in the meantime, most notably on "Highwayman" with Johnny Cash, Waylon Jennings and Willie Nelson.
I Would Like to See You Again is the 57th album by American country singer Johnny Cash, released on Columbia Records in 1978.
 The title track peaked at #12 on the singles chart, while "There Ain't No Good Chain Gang" reached #2; the album itself peaked at #23.
 The album features a pair of duets with Waylon Jennings, one of which was the "There Ain't No Good Chain Gang" single; it was one of Cash's first collaborations with Jennings, and the two recorded songs together throughout the 1980s, including a separate album entitled "Heroes".
 Cash and Jennings would also work together as The Highwaymen with Willie Nelson and Kris Kristofferson.
The Highwaymen was a country music supergroup composed of four of the genre's biggest artists well known for their pioneering influence on the outlaw country subgenre: Johnny Cash, Waylon Jennings, Willie Nelson, and Kris Kristofferson.
 Active as a group between 1985 and 1995, these four artists recorded three major label albums as The Highwaymen: two on Columbia Records and one for Liberty Records.
 Their Columbia works produced three chart singles, including the number one "Highwayman" in 1985.
"Highwayman" is a song written by American singer-songwriter Jimmy Webb, about a soul with incarnations in four different places in time and history: as a highwayman, a sailor, a construction worker on the Hoover Dam, and finally as a captain of a starship.
 The song was influenced by the real-life hanged highwayman Jonathan Wild.
 The dam builder verse alludes to the deaths of over one hundred men during the construction of Hoover Dam near Boulder City, Nevada.
 Webb first recorded the song on his album "El Mirage", released in May 1977.
 The following year, Glen Campbell recorded his version, which was released on his 1979 album "Highwayman".
 In 1985, the song became the inspiration for the naming of the supergroup The Highwaymen, which featured Johnny Cash, Waylon Jennings, Willie Nelson, and Kris Kristofferson.
 Their first album, "Highwayman", became a number one platinum-selling album, and their version of the song went to number one on the Hot Country Songs "Billboard" chart in a twenty-week run.
 Their version earned Webb a Grammy Award for Best Country Song in 1986.
 The song has since been recorded by other artists.
 Webb himself included a different version on his 1996 album "Ten Easy Pieces", a live version on his 2007 album "Live and at Large", and a duet version with Mark Knopfler on 2010 album "Just Across the River".
One Piece at a Time is the 54th album by American country singer Johnny Cash, released in 1976 on Columbia Records. "
One Piece at a Time," which was a #1 hit, is a humorous tale of an auto worker on the Detroit assembly line who puts together a car out of parts he swipes from the plant.
 "Sold Out of Flag Poles" also charted as a single, reaching #29 on the country singles charts.
 "Committed to Parkview", a Cash original, would be re-recorded in 1985 by Cash, Waylon Jennings, Kris Kristofferson and Willie Nelson, collectively known as The Highwaymen, on their first album, "Highwayman"; it is one of the few country songs sung from the perspective of a patient at a mental hospital.
Kristoffer Kristofferson (born June 22, 1936) is an American singer-songwriter, musician, and actor.
 He wrote and recorded the songs "Me and Bobby McGee", "For the Good Times", "Sunday Mornin' Comin' Down", and "Help Me Make It Through the Night".
 Kristofferson composed his own songs and collaborated with Nashville songwriters such as Shel Silverstein.
 In 1985, Kristofferson joined fellow country artists Waylon Jennings, Willie Nelson, and Johnny Cash in forming the country music supergroup The Highwaymen.
Rockabilly Blues is the 64th album by American country singer Johnny Cash, released on Columbia Records in 1980.
 Highlights include "Cold Lonesome Morning," which had some minor chart success (No. 53 in the country charts), "Without Love," by his son-in-law, Nick Lowe, and a cover of the witty "The Twentieth Century is Almost Over."
 The first two of the aforementioned songs were the only singles from the album, though "Without Love" hardly enjoyed any chart success, peaking at No. 78.
 "The Twentieth Century is Almost Over" was re-recorded five years later by Cash and Waylon Jennings, Willie Nelson and Kris Kristofferson, collectively known as The Highwaymen, on their first album entitled "Highwayman", though it was, in essence, a duet with Nelson.
El Mirage is the sixth album by American singer-songwriter Jimmy Webb, released in May 1977 by Atlantic Records.
 This was the first album for which Webb handed production and arrangement duties on to another person, George Martin, producer of The Beatles.
 The album is notable for containing "The Highwayman", a song that later provided both the name and first hit for The Highwaymen, a country supergroup comprising Johnny Cash, Waylon Jennings, Kris Kristofferson, and Willie Nelson.
 Jennings also recorded the track "If You See Me Getting Smaller" for his album "Ol Waylon" (1977).
