The British singer incurred the wrath of concertgoers at Munich's on3 live event as he began performing Deutschland Uber Alles, a part of Deutschlandlied used for German propaganda under Nazi rule. The Babyshambles frontman, known for his former relationship with model Kate Moss and well-publicised drug use, was booed at by the angry crowd.
Bavarian broadcasters Bayerischer Rundfunk pulled the show from the airwaves moments after his performance of the anthem. The tunes of Deutschland Uber Alles have not been sung since World War II due to its Nazi association.
Now, in a statement released to Sky News Online, his spokeswoman said the singer 'wanted to celebrate his appearance in Munich by assimilating and integrating with the crowd, something he tries to do wherever he goes."
She added: "He was unaware of the controversy surrounding the German National anthem and he deeply apologises if he has caused any offence." The statement went on to say: "Pete himself is from Jewish descent and has fought against racism and fascism with numerous organisations including Love Music Hate Racism."
