Addition to Wilde Gesellen. It comes rather from the socialist/anarchist roots of the National Socialists. Written in 1921, it was a favourite among the SAJD (Syndicalistic-Anarchist Youth of Germany). It was born as an anarchist song.
Mind: addition, not correction, what Wilfried writes remains true.

If one looks into the songbook of the Hitler Youth one can see a lot of fine old songs with not at all nationalistic roots. Union songs for instance. The Nazis took what was popular and adapted it to their cause, even if it meant changing the lyrics or lying. "Author unknown" added to the Loreley song is one such lie.
