Rockabilly was most popular with country fans in the 1950s, and 1956 could be called the year of rockabilly in country music. Rockabilly was an early form of rock and roll, an upbeat combination of blues and country music. The number two, three and four songs on Billboard's charts for that year were Elvis Presley, "Heartbreak Hotel"; Johnny Cash, "I Walk the Line"; and Carl Perkins, "Blue Suede Shoes" Thumper Jones (George Jones) Cash and Presley placed songs in the top 5 in 1958 with No. 3 "Guess Things Happen That Way/Come In, Stranger" by Cash, and No. 5 by Presley "Don't/I Beg of You." Presley acknowledged the influence of rhythm and blues artists and his style, saying "The colored folk been singin' and playin' it just the way I'm doin' it now, man for more years than I know." Within a few years, many rockabilly musicians returned to a more mainstream style or had defined their own unique style.
Folk songs sung in Australia between the 1780s and 1920s, based around such themes as the struggle against government tyranny, or the lives of bushrangers, swagmen, drovers, stockmen and shearers, continue to influence the genre. This strain of Australian country, with lyrics focusing on Australian subjects, is generally known as "bush music" or "bush band music". "Waltzing Matilda", often regarded as Australia's unofficial national anthem, is a quintessential Australian country song, influenced more by British and Irish folk ballads than by American country and western music. The lyrics were composed by the poet Banjo Paterson in 1895. Other popular songs from this tradition include "The Wild Colonial Boy", "Click Go the Shears", "The Queensland Drover" and "The Dying Stockman". Later themes which endure to the present include the experiences of war, of droughts and flooding rains, of Aboriginality and of the railways and trucking routes which link Australia's vast distances. https://www.youtube.com/watch?v=Uj5JQNLFSgA
