"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?
Willie Nelson Willie Hugh Nelson (born April 29, 1933) is an American musician, singer, songwriter, author, poet, actor, and activist. The critical success of the album "Shotgun Willie" (1973), combined with the critical and commercial success of "Red Headed Stranger" (1975) and "Stardust" (1978), made Nelson one of the most recognized artists in country music. He was one of the main figures of outlaw country, a subgenre of country music that developed in the late 1960s as a reaction to the conservative restrictions of the Nashville sound. Nelson has acted in over 30 films, co-authored several books, and has been involved in activism for the use of biofuels and the legalization of marijuana.
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)
