"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.
Parlour music Parlour music is a type of popular music which, as the name suggests, is intended to be performed in the parlours of middle-class homes by amateur singers and pianists. Disseminated as sheet music, its heyday came in the 19th century, as a result of a steady increase in the number of households with enough surplus cash to purchase musical instruments and instruction in music, and with the leisure time and cultural motivation to engage in recreational music-making. Its popularity waned in the 20th century as the phonograph record and radio replaced sheet music as the most common method of dissemination of popular music. This is the middlebrow and lowbrow music from which European classical music began to gradually and eventually self-consciously distance itself beginning around 1790. (1989, p. 4, 17-18, 321)
