Editing Vienna New Year's Concert (section)

=== Encores ===
There were no encores in 1939, and sources indicate that encores were not instituted until 1945. Clemens Krauss almost always included "Perpetuum mobile" either on the concert or as an encore. The waltz "The Blue Danube" was not performed until 1945, and then as an encore. The "[[Radetzky March]]" was first performed in 1946, as an encore. Until 1958, these last two pieces were often but not always given as encores. Since that year, their position as twin encores has become inviolable tradition, with two exceptions:
* In 1967, [[Willi Boskovsky]] made "The Blue Danube" part of his concert program to commemorate the work's centenary; its encore position was occupied by Johann Strauss II's "{{ill|Unter Donner und Blitz|de}}, {{lang|de|polka schnell}}, Op. 324. Additionally, an actor impersonating the composer of the work appeared during the concert.
* In 2005, [[Lorin Maazel]] and the orchestra concluded the program with "The Blue Danube", omitting the "Radetzky March" as a mark of respect to the victims of the [[2004 Indian Ocean earthquake and tsunami]]. One unannounced encore, a gallop or {{lang|de|polka schnell}}, is always placed before "The Blue Danube", and after the final announced work on the printed concert programme. It has also been a jocular composition.
