"The Twentieth Century is Almost Over" was re-recorded five years later by Cash and Waylon Jennings,  Kris Kristofferson, and  Willie Nelson, one of the most recognized artists in what type of music?
Rockabilly Blues 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.
Answer song An answer song (or response song) is, as the name suggests, a song (usually a recorded track) made in answer to a previous song, normally by another artist. It is also known as an answer record. The concept became widespread in blues and R&B recorded music in the 1930s through 1950s. Answer songs were also extremely popular in country music in the 1950s and 1960s, most often as female responses to an original hit by a male artist.
