Nice work, Sir, and thanks for taking the time to do that repetitive task!. I have only heard China's up to now.If I have missed out any country please add them.
Thanks for the amplification.its interesting to listen to "March of the Volunteers" in English (later adopted as PRC anthem), by Paul Bobeson in 1941 an African American bass
The lyrics of ROC anthem is actually a brief speech by Dr Sun Yat-Sen
ROK (S Korea) govmt in exile once used Auld Lang Syne melody for their anthem when in China.
March of the Volunteers was composed by Nie Er to a text by Tian Han in 1934.[5] Popular stories suggest, however, that Tian wrote it on a tobacco paper after being arrested in Shanghai and thrown into a Kuomintang (KMT) jail in 1935. The song was featured as the theme song of the 1935 patriotic film Sons and Daughters in a Time of Storm, also known as "Children of the Storm," a story about an intellectual who leaves to fight in the Second Sino-Japanese War. It was one of many songs that were promoted secretly among the population as part of the anti-Japanese resistance during the "left-wing cinema movement" (1931-37).[6] The song was released as an album by the Pathé label of EMI in 1935.
