The long and the short of it is that Pete Doherty shocked a German crowd this weekend when he sang a Nazi anthem. I was going to write it all up but I'm not sure I'm going to be able to say it better than the Daily Swarm did, so have a look at what they posted on the matter below.

Peter Doherty was born in Hexham, Northumberland, England, the son of Jacqueline (Michels), who was of paternal Jewish descent, and Peter John Doherty, who was of Irish descent.

Rocker Pete Doherty was hauled off stage at a weekend music festival in Germany after he began signing Nazi anthem “Deutschland, Deutschland ueber alles” during his set, reports said on Monday. Revellers at the on3 festival in Munich booed and shouted at Doherty, but he carried on singing until organisers removed him from the stage, Bavaria’s TZ newspaper reported. Doherty’s tirade was broadcast live on Bavarian public radio, the festival’s organisers. “We decided to stop Peter Doherty’s appearance on stage as quickly as possible,” organisers Bayerischer Rundfunk said in a statement. While the verse is not banned in Germany, it has not been sung since World War II because of its close links with Adolf Hitler.
And the subsequent and quasi-inevitable apology, from NME:
"[He] wanted to celebrate his appearance in Munich by assimilating and integrating with the crowd, something he tries do wherever he goes,” she explained. “He was unaware of the controversy surrounding the German national anthem and he deeply apologises if he has caused any offense,” the singer’s spokesperson continued." Peter himself is from Jewish descent and has fought against racism and fascism with numerous organisations including Love Music Hate Racism,” she added. “This is a subject he feels very strongly about.”
