In what was most likely a drug-induced action, Pete Doherty infuriated fans at German music festival by singing the banned Nazi verse of the national anthem.

The rocker took to the stage at the Munich event last Saturday and launched into a rendition of “Deutschlandlied” (translated: “The Song of Germany”). As soon as fans heard the first verse - which has been banned since the end of World War II because of its use during the Nazi regime by Adolf Hitler and its reference to racial superiority - they began to jeer and heckle Pete.

His performance was allowed to continue for five more songs before organizers made him leave the stage and the live radio broadcast was cut, prompting Pete to hurl his microphone at the concert’s host.

A statement released by the organizers said, “As the British say, ‘We are not amused.’ Unfortunately, it was unforeseeable. Live is live.”

Only the third verse of the national anthem is allowed to be sung in Germany. The first stanza of the anthem translates as, “Germany, Germany above all / Above all in the world. When, for protection and defence, it always takes a brotherly stand together. / From the Meuse to the Memel, From the Adige to the Belt, Germany, Germany above everything. Above everything in the world.”

Pete has admitted he grew up listening to songs about the Nazis because his father was an officer in the British army and the family lived at various garrisons.

“Growing up in army barracks I remember hearing a lot of army-related songs, mostly about Hitler’s genitalia, the quartermaster’s stores and one perennial favorite that went something like, ‘left, right, left’, which I could always hear belting out from the parade square.”
