Almost spilled my coffee seeing this
OK, I understand you might be clueless in this topic, but Russians played you like a fiddle. Where to start...
1. This is supposed to be an anthem of the Luftwaffe? LOL.? Even that weird channel AZ points to writes in Russian: "Not an official anthem of the Luftwaffe". Because it´s not the anthem of the Luftwaffe.
2. National anthems - what kind of Russian bulls**t YT channel is that? It uploaded precisely 1 video of a song which is not even an anthem
3. The music in video linked, that supposed "Anthem of the Luftwaffe" is song by Dutch band Bots, recorded in 1951. Needless to say, by this time Luftwaffe didnt even exist. Here you can see these Nazis in action, but be warned, its pretty hardcore, not for everybody!
4. The song itself is actually much older. It´s an old drinking song from Bretagne, which became very popular in early 20th century as "Son ar chirst" (Song of the cider). And is still popular till today, got more than 20 new coverversions in past 10 years.
