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
Following World War II a growth phase for Canadian bands was experienced, this time among school bands. Rapid advances in the inclusion of instrumental music study in formal school curricula brought about fundamental changes to the philosophy of the band movement and the type of repertoire available. The CHUM Chart debuted on May 27, 1957, under the name CHUM's Weekly Hit Parade, was in response to the fast-growing diversity of music that needed to be subdivided and categorized. The CHUM charts were the longest-running Top 40 chart in Canada ending in 1986.
By the end of World War II, "mountaineer" string band music known as bluegrass had emerged when Bill Monroe joined with Lester Flatt and Earl Scruggs, introduced by Roy Acuff at the Grand Ole Opry. That was the ordination of bluegrass music and how Bill Monroe became to be known as the "Father of Country Music." Gospel music, too, remained a popular component of bluegrass and other sorts of country music. Red Foley, the biggest country star following World War II, had one of the first million-selling gospel hits ("Peace in the Valley") and also sang boogie, blues and rockabilly. In the post-war period, country music was called "folk" in the trades, and "hillbilly" within the industry. In 1944, The Billboard replaced the term "hillbilly" with "folk songs and blues," and switched to "country" or "country and Western" in 1949. https://www.youtube.com/watch?v=hyNAvdnZ5Ec
