"A deeply private and polite man" whose own brand of poetry could be sung to music in only one way -- by Leonard Cohen himself.  Looking at the scope of his work, one would never insult his character with enormous gawdy 'loud' murals on the side of any building.  Those types of images scream 'look at the sponsor for this mural', not the works nor the personality of Mr. Cohen. Did he ever write anything to deserve this? Suzanne takes me down to ... the side of a multi-storey building? Like a bird on a wire ... overshadowed by a looming multi-storey façade? I doubt Mr. Cohen would want any such gawdy tribute because so much of his work 'commented' on the fleeting nature ... and fragile impermanence .. of life.  Any tribute should remember the quiet reflective nature of the man and his work.  In fact, his body of work is the most appropriate 'tribute',  reflecting the man himself. No need for brazen showy 'kitsch'.
