This is an apolitical forum for discussions on the Axis nations and related topics hosted by the Axis History Factbook in cooperation with Christian Ankerstjerne’s Panzerworld and Christoph Awender's WW2 day by day.
Founded in 1999.
Not sure whether the march was tied to the Hapag or not, but it's interesting to note who was "hiding" under the pseudonyms of Lemeau and Faneau - two well known German Jewish bandleaders/composers: Lemeau = Felix Lehmann (best known as Fred Bird), Faneau = Hans Ailbout.
The march was probably composed shortly before it was recorded (1928).
There were at least five more marches with that slogan: "Mein Feld ist die Welt!" Op. 34 by Max Jancovius (1900), "Mein Feld die Welt" Op. 499 by Carl Michael Ziehrer (1900), "Mein Feld ist die Welt" Op. 128 by F. Fickl (1906), "Mein Feld die Welt" by Hermann Ludwig Blankenburg (1911) and "Mein Feld die Welt" by Emil Toft (date unknown; Toft died in 1918). None of them was tied to the Hapag, as far as I know.
He was half-Jewish and had a special Goebbels' permission to continue working during the Nazi rule. But his name rarely appeared on records after 1933. (The Nazis made exceptions for exceptional musicians whose talent could be used for propaganda purposes; for example, famous lyricist Bruno Balz, a homosexual, was also allowed to continue working, after being arrested several times because of his sexual orientation.)
