"Sei gesegnet ohne Ende" (English translation: "Be Blessed Without End"), also known as the ″Kernstock-Hymne″, is a German language song that was the national anthem of Austria from 1929 until 1938.
 Written by Ottokar Kernstock, it was sung to the famous tune of "Gott erhalte Franz den Kaiser" by Joseph Haydn that is also used for the "Deutschlandlied", since 1922 the national anthem of Germany.
(Franz) Joseph Haydn ( ; ] ; 31 March 173231 May 1809) was an Austrian composer of the Classical period.
 He was instrumental in the development of chamber music such as the piano trio and his contributions to musical form have earned him the epithets "Father of the Symphony" and "Father of the String Quartet".
Alexander Aleksandrovich Alyabyev (Russian: Алекса́ндр Алекса́ндрович Аля́бьев ; 15 August [O.S. 4 August] 1787 6 March [O.S. 22 February] 1851 ), also rendered as Alabiev or Alabieff, was a Russian composer known as one of the fathers of the Russian art song.
 He wrote seven operas, twenty musical comedies, a symphony, three string quartets, more than 200 songs, and many other pieces.
The Symphony No. 9 in D minor, Op.
 125, is the final complete symphony composed from 1822 to 1824 by the German composer Ludwig van Beethoven.
 It was first performed in Vienna on 7 May 1824.
 The symphony is one of the best-known works in common practice music.
 It is widely viewed by critics as one of Beethoven's greatest works, the pinnacle of musical Classicism, and one of the greatest compositions in the western musical canon.
 The symphony was the first example of a major composer using voices in a symphony (thus making it a choral symphony).
 The words are sung during the final movement by four vocal soloists and a chorus.
 They were taken from the "Ode to Joy", a poem written by Friedrich Schiller in 1785 and revised in 1803, with text additions made by the composer.
 In the 2010s, it stands as one of the most performed symphonies in the world.
"When A Child Is Born" is a popular Christmas song.
 The original melody was "Soleado", a tune from 1974 by (alias Zacar), composer for Italy's Daniel Sentacruz Ensemble, and Dario Baldan Bembo.
 The tune was based on Damicco's earlier tune "Le rose blu" published in 1972.
 The English language lyrics were written a few years later by Fred Jay (Friedrich Alex Jacobson IPI number 00015195204, who wrote many hits for Boney M such as Rasputin and Ma Baker).
 They do not make specific mention of Christmas but the importance they attach to looking forward to the birth of one particular child somewhere, anywhere, suggests a reference to the birth of Jesus Christ, and the citing of "a tiny star" that "lights up way up high" may allude to the Star of Bethlehem.
 Fred Jay's lyrics have been sung by many artists, most successfully by Johnny Mathis in 1976.

"Lloyd George Knew My Father" is a 20th-century English schoolboy folk song.
 The simple lyrics consist of the phrase ""Lloyd George knew my father/Father knew Lloyd George"" sung to the tune "Onward, Christian Soldiers".
 In the schoolboy song, the two lines referring to Lloyd George are repeated incessantly, typically by groups of schoolboys on a bus or similar setting, until boredom sets in.
 There are no lyrics other than those two lines.
 The song gains much of its notoriety from the irony inevitable in the clash between the song's flippant lyrics and Sabine Baring-Gould's classic hymn from which Arthur Sullivan's tune is inextricable.
 It is also commonly sung to the tune of "Land of Hope and Glory".
Wilson Sawyer (1917–1979) was an American composer, arranger and musician.
 Born in Traverse City, Michigan, he showed musical talent at an early age and studied music at the University of Michigan.
 Sawyer conducted the University's Women's Glee Club and led the Bill Sawyer Orchestra, a big band that was featured on WMAQ's "Fitch Summer Bandwagon" on July 7, 1940.
 He composed several arrangements of choral works; popular songs for Perry Como, Fred Waring and Ray Eberle; music for the "Alaskan Stampede," a Leo Seltzer produced "musical extravaganza on ice" c. 1944, and an opera based on Mark Twain's Tom Sawyer.
 He is best known for composing Symphony No. 1, known as the Alaskan Symphony, at Gypsy Trail, Carmel, New York in 1945.
 The work includes text from the "Spell of the Yukon" by Robert W. Service sung by a baritone soloist in the third movement, as well as other thematic inspirations drawn from his study of the climate, topography and history of the then-territory.
 The Alaskan Symphony was first performed in December 1945 by the American Symphony Orchestra and was broadcast across the United States and to overseas armed services at that time.
 Wilson Sawyer conducted the piece and Gov. Ernest Gruening of Alaska was guest speaker on the program.
 At Gruening's request, the original score was placed in the Alaskan Museum of Natural History [Alaska Historical Library and Museum] in Juneau, Alaska.
 In 1960, Sawyer's wife Maxine was diagnosed with spinal cancer and they moved to Pawling, New York where he operated a chicken farm and laundromat.
 He continued to compose.
 The Alaskan Symphony was performed by the Hudson Valley Philharmonic in 1975 with Sawyer again conducting even though he had recently suffered a stroke.
 Sawyer revised the Symphony in 1977, making substantial cuts to the fourth movement among other edits.
 The revised Alaskan Symphony was premiered by the Juneau Symphony on June 14, 2008, conducted by music director Kyle Wiley Pickett.
"Solidarity Forever", written by Ralph Chaplin in 1915, is perhaps the most famous union anthem.
 It is sung to the tune of "John Brown's Body" and "The Battle Hymn of the Republic".
 Although it was written as a song for the Industrial Workers of the World (IWW), other union movements, such as the AFL-CIO, have adopted the song as their own.
 The song has been performed by musicians such as Utah Phillips, Pete Seeger, and was redone by Emcee Lynx and The Nightwatchman.
 It is still commonly sung at union meetings and rallies in the United States, Australia and Canada, and has also been sung at conferences of the Australian Labor Party and the Canadian New Democratic Party.
 This may have also inspired the hymn of the consumer cooperative movement, "The Battle Hymn of Cooperation", which is sung to the same tune.
W. de Wycombe (Wicumbe, and perhaps Whichbury) (late thirteenth century) was an English composer and copyist of the Medieval era.
 He was precentor of the priory of Leominster in Herefordshire.
 It is possible that he was the composer of the most famous tune from medieval England, "Sumer is icumen in".
