I think what is British about me is my feelings and awareness of others and their situations. English people are always known to be well mannered and cold but we are not cold - we don't interfere in your situation. If we are heartbroken we don't scream in your face with tears - we go home and cry on our own.
It's much easier to wear a Chairman Mao button and shake your fists in the air and all that then to actually read the Communist manifesto and things like that and actually become involved in politics.
I guess the two Manifesto Communicating Vessels Mad Love and some of his poetry made a significant mark on me but as far as bringing a literary element into the music I see it as a much broader assimilation.
