LOL ! I must say, I had to look that up. Funny !
Horst Wessel (b. September 9, 1907, Bielefeld, Germany -- d. February 23, 1930, Berlin, Germany) joined the Nazi party in in 1926. He was killed by political enemies in a fight in his rooms in Berlin. Glorified as a martyr to the Nazi cause, his song became the offical Nazi anthem.
This was perhaps the most famous Nazi song of the war.
[Correction to previous note here. The Horst Wessel Song was not, as previously stated, the German song sung, famously, in the emotional scene Rick's Cafe Amercaine in Casablanca, only to be drowned out by the Marseillaise!. As several correspondents pointe out, that song was an older patriotic, but (non-Nazi song called Wacht am Rhein (The Watch on the Rhine)]

Translation
Flag high, ranks closed,
The S.A. marches with silent solid steps.
Comrades shot by the red front and reaction
march in spirit with us in our ranks.
The street free for the brown battalions,
The street free for the Storm Troopers.
Millions, full of hope, look up at the swastika;
The day breaks for freedom and for bread.
For the last time the call will now be blown;
For the struggle now we all stand ready.
Soon will fly Hitler-flags over every street;
Slavery will last only a short time longer.
Flag high, ranks closed,
The S.A. marches with silent solid steps.
Comrades shot by the red front and reaction
march in spirit with us in our ranks.
