Part 1: Edward Elgar's 'Cockaigne' Overture

Steam trains and coaches bring tourists to London; a military band plays on the steps of St Paul's; at Battersea funfair, people enjoy a water ride and a girl eats candyfloss; soldiers fire a cannon in Hyde Park; the Queen's Guards march in formation, as do street cleaners and sandwich-board men; street musicians play; women inspect a rack of London postcards; pigeons descend on Trafalgar square; traffic snarls up Piccadilly; boats float past St Paul's on the Thames.

Part 2: Christopher Whelen's 'London Moods'

Leather-clad bikers sit on the steps of St Paul's, before mounting their bikes and riding off; road traffic and restaurant signs; burgers and breakfasts are prepared and eaten; snack bars dispense food and drink from vending machines; people in a massage salon use belts and machines to keep in trim; people cram onto Underground lifts and escalators; a juke box plays; people in a fairground 'Rotor' are pinned to the walls by centrifugal forces.

Part 3: Ralph Vaughan Williams' 'A London Symphony'

A derelict Tube station, tower blocks, wild flowers growing on old bomb sites, a memorial to the First World War, with decaying wreaths laid at the foot of the statue of a soldier; the Houses of Parliament, St Paul's Cathedral at dusk; traffic and pedestrians cross the Thames.
