It's a celebration of the wealth, power and beauty of London, a city that looks significantly different now.

Here is the text of the original poem, as read on the programme from Westminster Bridge by Paul Farley, Poet-in-Residence at the Wordsworth Trust.

Composed Upon Westminster Bridge Sept 3, 1802 by William Wordsworth (1770-1850)

Earth has not any thing to shew 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 splendor 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 mightly heart is lying still!

The phrase 'smokeless air' may not ring true for many 21st Century Londoners.

As a result, poet Ian McMillan (commissioned by The Globe Theatre to write sonnets inspired by Wordsworth) came up with the following words to describe a London familiar with bike-couriers and ample amounts of litter.
