This is an old German song, traditionally played at funerals (tr: "Once, I had a comerade"). I was once told that it is associated with coal miners, though the first verse, which I know already, says "the drum called us to battle, we marched side by side, step for step". (I hasten to add that the song predates the Nazi era by many years.) But, I guess given German history from 1870 on, coal miners and veterans were largely overlapping subsets.
So as not to waste anyone's time, I should say that I ALREADY KNOW that the tune was used for the Spanish Civil War Republican song "Hans Beimler", and I ALREADY KNOW all those verses. What I am looking for, if they exist, is more verses to the original song (in German).
Vielleicht gibt es jemand der mir hilfen könnte.
Thanks,
James
