In 1960, when the Beatles (then an obscure Liverpudlian combo with five members, as opposed to their eventual "fab" four) were working in Hamburg, West Germany, they were influenced by a Bohemian "art school" set known as Exis (for "existentialists").
John Lennon's wife Cynthia recalled that Kirchherr was fascinated by the Beatles' "teddy-boy style", but that they, in turn, were "bowled over by her hip black clothes, her avant garde way of life, her photography and her sense of style" [REF].
