Eleanor Rigby picks up the rice in a church where a wedding has been, Lives in a dream. Waits at the window, wearing the facethat she keeps in a jar by the door, Who is it for? All the lonely people, where do they all come from?

   Well since my baby left me I found a new place to dwell It's down at the end of lonely street At Heartbreak Hotel.

There is no looking-glass here and I don't know what I am like now. I remember watching myself brush my hair and how my eyes looked back at me. The girl I saw was myself and yet not quite myself. Long ago when I was a child and very lonely I tried to kiss her. But the glass was between usöhard, cold and misted over with my breath.Now they havetaken everything away.What am I doing in this place and who am I?

I don't think it does any harm to the artist to be lonely as an artist.

Some people swim lakes, others climb flagpoles, some join monasteries, but we, my friends, who have considered suicide take our daily walk with death and are not lonely. In the end it brings more honesty and care than all the democratic parliaments of tricks.

These beauteous forms, Through a long absence, have not been to me As is a landscape to a blind man's eye: But oft, in lonely rooms, and 'mid the din Of towns and cities, I have owed to them, In hours of weariness, sensations sweet, Felt in the blood, and felt along the heart.
