I am helping a budday out who studies music. His task is to get a list of popular WW1 & WW2 songs, and preferably from many nations, not just america and germany. Luckily his teacher is an open minded fellow, so WW2 german songs are allowed as long as they do not have any reference to the holocaust.
As a bonus he may also add songs from before WW1 & even some important movies
here is what i have compiled for him so far:
-Erika
-Grenadier lied
-Westerwald marsch
-Fridericus Rex
-Red army choir - When the soldiers are singing
-Red army choir -The Sacred War
-On ne passe pas
-Kay kyser-praise the lord and pass the ammunition
-Blood on the risers
-It's A Long Way To Tipperary
-Vera lynn- We'll meet again (YES fh2 one

)
-La sagra di giarabub
So pass on some more please!
