Who is a carrier of tradition? Anybody who picks it up. What songs from World War II are the prroduct "of the people"? well, I'm not going t judge what should be called great or not, but "Lili Marlene" didn't come to the allied troops via Armed Forces radio or Stars and Stripes newspaper (see by Bill Mauldin; a great book, for at-the-time comments. sorry to be "academic" in these things, but I like to give backup on where I get my information), General Eisenhower admitted that he enjoyed the song "Dirty Gertie from Bizerte", and to this day, people are singing "Hitler has only got one ball". All three are still sung, but only one was commercially written, only one could possibly be played on the radio in the USA, and that one came from the other side. I'd bet that there are other examples, and less rude ones as well.
