London has blues.
It is there, if one looks closely
at Tower Bridge,
on the docks behind Tower Hotel,
greeting customers at the Best of India along Brick Lane,
on a plate at the Victoria and Albert,
down an alley off Portobello Road,
decorating not only the entry,
but the windows as well.
New York has a blue mosaic
outside one of the stores.
You must look up to see it,
although if the wind is blowing and you listen closely,
the tinkling of the blues can be heard.
Boston has a bit of blue
of the natural sort
