Probable attribution

A source trail connects this quotation to Albert Einstein and p. 31; spoken on hearing German marchers singing war songs. On p. 474 of Alice Calaprice's The Ultimate Quotable Einstein, she lists "we only use 10 percent of our brain" as a quote "misattributed to Einstein", perhaps this is the source of the misquote?
