The Horst Wessel Lied was the anthem of the Nazi Party of Germany, chosen to glorify Horst Wessel as a Nazi martyr. It is banned in Germany.
The melody was used as the theme music to the popular computer game Wolfenstein 3D in the early 1990s.
In 2005, the Alberta branch of the Royal Canadian Legion accidentally used the Horst Wessel Lied as the theme music in an advertising campaign for their fundraising lottery.
Melody
Because the melody was used in many other songs, its origin is widely disputed, but it is believed that it originally came from Etienne Méhul's operaJoseph from 1807.
