The Man from Snowy River is an Australian adventure drama television series based on Banjo Paterson's poem "The Man from Snowy River".

"Waltzing Matilda" is Australia's best-known bush ballad, and has been described as the country's "unofficial national anthem".
Dionysios Solomos (Greek: Διονύσιος Σολωμός ] ; 8 April 1798 – 9 February 1857) was a Greek poet from Zakynthos.
 He is best known for writing the "Hymn to Liberty" (Greek: Ὕμνος εις την Ἐλευθερίαν , "Ýmnos eis tīn Eleutherían"), of which the first two stanzas, set to music by Nikolaos Mantzaros, became the Greek national anthem in 1865.
 He was the central figure of the Heptanese School of poetry, and is considered the national poet of Greece—not only because he wrote the national anthem, but also because he contributed to the preservation of earlier poetic tradition and highlighted its usefulness to modern literature.
 Other notable poems include "Ὁ Κρητικός" ("Τhe Cretan"), "Ἐλεύθεροι Πολιορκημένοι" ("The Free Besieged") and others.
 A characteristic of his work is that no poem except the "Hymn to Liberty" was completed, and almost nothing was published during his lifetime.
"Giovinezza" (] ; Italian for "youth") is the official hymn of the Italian National Fascist Party, regime, and army, and was the unofficial national anthem of Italy between 1924 and 1943.
 Although often sung with the official national anthem Marcia Reale, some sources consider Giovinezza to have supplanted the Royal March as the "de facto" national anthem ("Inno della Patria") of Italy, to the dismay of Victor Emmanuel III of Italy—a powerful symbol of the diarchy between the King and Mussolini.
 It was subsequently the official anthem of the Italian Social Republic.
