Should france force anyone from an immigrant background to sing the marseillaise with its chorus calling on soldiers to water the fields with " impure blood " ?
Days earlier , she tried to reclaim the value of patriotism by arguing that socialists should sing the " marseillaise " , the national anthem , at party meetings , and that french people should keep the tricolour in their homes .
I can never help blubbing at the " battle of the anthems " scene , when the nazi soldiers are drowned out in their jingoistic singing by a hotch-potch of pickpockets , refugees and jews belting out " la marseillaise " .
