Composed Upon Westminster Bridge by William Wordsworth

Earth has not anything to show more fair:
Dull would he be of soul who could pass by
A sight so touching in its majesty:
This City now doth, like a garment, wear
The beauty of the morning; silent, bare,
Ships, towers, domes, theatres, and temples lie
Open unto the fields, and to the sky;
All bright and glittering in the smokeless air.
Never did sun more beautifully steep
In his first splendour, valley, rock, or hill;
Ne'er saw I, never felt, a calm so deep!
The river glideth at his own sweet will:
Dear God! the very houses seem asleep;
And all that mighty heart is lying still!

Wordsworth's Return to Westminster Bridge by Ian MacMillan

Earth has not any thing to show more fair
(Well, to be honest, actually it does)
than this view of floating litter through the city air
I can't hear myself think above the buzz
Of motorcycle couriers shouting loud
Obscenities to the shuffling crowd
Who move across this bridge as slow as sludge
Who point and gawp and spit and swear and trudge
Never did sun more grudgingly shine
On the torn up timetables of cancelled trains
Which drop like confetti on empty bottles of wine
Smashed by those smashed out of their brains
Last night as Big Ben's chimes rang forth
And I'm glad that I live in the civilised North!
