LONDON, July 27 (Reuters) - Seven teenagers lit the Olympic

cauldron on Friday, at an opening ceremony starring the queen

and seen by millions around the world, in a touching finale to a

high-octane, musical celebration of British history and culture.

True to the London Games' motto of 'Inspire a Generation',

organisers put unknown youngsters in the global limelight rather

than established sporting greats in the closing act of a madcap

four hours of comedy, spectacle, noise and emotion.

"I declare open the Games of London celebrating the 30th

Olympiad of the modern era," said Queen Elizabeth, the

86-year-old monarch, followed by a fanfare and explosion of

fireworks.

The ceremony on a cool, cloudy but dry London night kicks

off 16 days of sporting thrills and spills up and down the

country, as more than 16,000 athletes from 204 countries vie for

the Holy Grail of sport - Olympic gold.

Celebrating her 60th year on the throne this year, the

monarch played a starring role in a ceremony which film director

Danny Boyle turned into an unabashed celebration of the host

nation stamped with an unmistakeably cinematic style.

Early on in the show, which ran well over time, Her Majesty

appeared in a short, tongue-in-cheek film also starring Daniel

Craig in his role as James Bond.

Wearing his trademark tuxedo, 007 enters Buckingham Palace

and the queen, with two corgis at her feet, turns from a writing

desk and says simply: "Good evening, Mr Bond".

The moment drew a huge cheer from the crowd, not used to

seeing Her Majesty play such an informal part in proceedings,

and coincided with a resurgence in the royal family's popularity

following the 2011 wedding of Prince William and Kate Middleton.

Doubles of Bond and the queen then parachuted from a

helicopter above the stadium, built on the Olympic Park in a

once derelict area of London's East End, before schoolchildren

sang the national anthem and the Union flag was raised.

LOST IN TRANSLATION?

The quintessentially British flavour to the ceremony,

accompanied by a stunning soundtrack of hits from Elgar to U2,

caused plenty of confusion among international journalists

struggling to describe it to readers back home.

"It couldn't get any more British if it came drenched in

tea," quipped the Hollywood Reporter movie magazine.

But others from abroad warmed to Boyle's vision.

"It really played to what Britain does best," said Sarah

Clarke, a visitor from South Africa, as she left the stadium

after the show. "It was a British ceremony but absolutely we

felt included."

The ceremony, inspired by Shakespeare's "The Tempest", began

with Britain's first Tour de France winner Bradley Wiggins

ringing a giant 23-tonne Olympic bell.

Played out before world leaders, European royalty and

dignitaries including U.S. First Lady Michelle Obama, the show

switched to the playful recreation of an English rural idyll

with grassy meadows, fences, a water mill and maypoles.

A cast including shepherdesses, sheep, geese, dogs and a

village cricket team filled the stage during the one-hour

prologue to the show that included a dramatic, low-level

fly-past by the jets of the Royal Air Force's Red Arrows stunt

team.

After "England's green and pleasant land" came the "dark

Satanic mills" of William Blake's famous poem.

Titled "Pandemonium", the next phase saw the grass uprooted

and fences torn down to be replaced by a blackened landscape of

looms and foundries that conjured the Industrial Revolution.

To the deafening beat of hundreds of drummers, giant

chimneys rose from the ground and began to belch smoke as a

small army of volunteers, dressed as 19th century factory

workers, forged one of the five Olympic rings.

The giant orb was raised to the sky to join the four others,

letting off a fountain of sparks and drawing gasps from many in

the audience.

All around, especially designed "pixel" light boxes

installed next to every seat accompanied each scene and created

giant images of waves, flags and words.

In the second of three "acts", Boyle paid homage to the

National Health Service, an emotive subject in Britain where

people hold the right to free health care close to their hearts.

Hundreds of dancing and roller-skating nurses and doctors

pushed beds on to the now empty stage and when the beds were

illuminated, they spelled "GOSH" for the cherished Great Ormond

Street children's hospital in London.

"The atmosphere was electric coming out into the stadium -

like we could take over the world with our beds!", said Rachel

Dobbin, a speech and language therapist from London who

performed as a nurse in the ceremony.

SPOOKY VILLAINS

Giant representations of famous villains from English

literature, including JM Barrie's Captain Hook, JK Rowling's

Voldemort and Ian Fleming's Childcatcher, rose from their beds.

They were quickly vanquished by dozens of Mary Poppins

characters descending from cables criss-crossing the stadium

roof, carrying brightly illuminated umbrellas.

Comedian Rowan Atkinson, adopting the globally recognised

character of mischievous Mr Bean, brought the house down as he

joined the London Symphony Orchestra playing a single note

throughout the score of the Olympic film "Chariots of Fire".

The final act, starring hundreds of young nightclubbing

dancers, was a breathless journey through popular British

culture over the last five decades featuring music from everyone

from the Sex Pistols to Queen and the Jam to the Who.

Sitting at a computer outside a small house on stage was Tim

Berners-Lee, the Londoner who invented the worldwide web and

enabled the explosion of social networking that is playing a

major part at the London Games.

Mid-ceremony he tweeted to his almost 83,000 followers "This

is for everyone" which also projected across the spectators.

Next came the parade of athletes, with the Greek team

keeping up Olympic tradition and leading out thousands of

competitors dressed in colourful national costumes.

They marched around the stadium in double-quick time, urged

on by the up-tempo beats of the Bee Gees band and others. The

world's fastest man Usain Bolt strode confidently with the

Jamaican flag while playing up to cameras and cheering fans.

Libya and Egypt represented a new chapter in their histories

after the tumultuous events of the Arab Spring while the first

ever female Olympic athletes from Saudi Arabia, Brunei and Qatar

made appearances.

Britain, dressed in white and gold and hoping to repeat its

medals success of Beijing in 2008, entered last to thunderous

roars and the thumping strains of David Bowie's lyrics "We Can

Be Heroes" as ticker tape floated down from the roof.

Boxing's most famous fighter Muhammad Ali briefly appeared

to hold the Olympic flag, looking frail, wearing dark glasses

and leaning on his wife.

The Olympic torch, ending an 8,000-mile odyssey across the

country, was driven in a speedboat up the River Thames by former

England soccer captain David Beckham and handed to Britain's

most successful Olympian Steve Redgrave.

He then passed it on to seven youngsters - Callum Airlie,

Jordan Duckitt, Desiree Henry, Katie Kirk, Cameron MacRitchie,

Aidan Reynolds and Adelle Tracey - who performed a lap of honour

before approaching the centre of the stage.

Surrounded by thousands of athletes, they lit some of the

200-plus copper petals which rose on stalks to form a single

burning "flower".

Ex-Beatle Paul McCartney rounded off a night when music

played non-stop, and at concerts across the capital, with a

nostalgic sing-along of his old band's hit "Hey Jude".
