"Imagine" by John Lennon is now being sung by a Korean quartet.

This is quite a picture.

Huge applause for the British team - led by Olympic champion Lizzy Yarnold.

She was aiming to carry the flag one-handed around the entire arena - she certainly managed it around the first bend.

The ‘Olympic athletes from Russia’ squad followed soon after. No booing, but notably not applause either.

More from Thomas Bach, the crowd are loving this.

He continues: "A great example of this unifying power is the joint march here tonight of the two teams from the National Olympic Committees of the Republic of Korea and the Democratic People’s Republic of Korea. We thank you.

"All the athletes around me, all the spectators here in the stadium, and all Olympic fans watching around the world… we are all touched by this wonderful gesture. We all join and support you in your message of peace.

"United in our diversity, we are stronger than all the forces that want to divide us. Two years ago in Rio de Janeiro, with the first ever Refugee Olympic Team, the IOC sent a powerful message of hope to the world. Now in Pyeongchang, the athletes from the teams of the ROK and DPRK, by marching together, send a powerful message of peace to the world. Let us share this Olympic experience with the world. Let’s go together, Pyeongchang!"

More from IOC president Thomas Bach, who gives a uniting message to the athletes.

He says: "Over the next days, the world will be looking to you for inspiration. You will inspire us all to live together in peace and harmony despite all our differences. You will inspire us by competing for the highest honour in the Olympic spirit of excellence, respect and fair play.

"You can only really enjoy your Olympic performance if you respect the rules, and stay clean. Only then will your lifelong memories be the memories of a true and worthy Olympian. While you compete with each other, you live peacefully together in the Olympic Village, respecting the same rules, sharing your meals and your emotions with your fellow athletes.

"This is how you show that in sport we are all equal. This is how you show the unique power of sport to unite people."

Here is Thomas Bach, president of the International Olympic Committee.

He says: "This is the moment that we have all been waiting for: the first Olympic Games on snow and ice in the Republic of Korea. This is the moment that the Organising Committee, the public authorities and so many people have been working for with great dedication and commitment. You all can be very proud tonight.

"Now is the time for Pyeongchang! Thank you to everyone who has made this moment possible. A special thanks goes to the thousands of volunteers who have welcomed us so warmly: Thank you, volunteers. Dear athletes, now, it’s your turn! This will be the competition of your life."

There is nothing like walking out in a stadium for an opening ceremony and feeling the camaradarie between all of the teams.

It's a picture of colour with all those athletes out there to do one thing and one thing only, and that is to deliver the best performance they can.

Jackie Hodson: Finding all this surprisingly emotional.

Toran Shaw: Did I just see one of the Korean athletes do the Mobot?

Claire: American athletes have heated jackets, Tongan flag bearer has no shirt on & a skirt.

Some more of the stunning ceremony that is going on at the moment.

BBC's Caroline Chapman, who is in Pyeongchang, had a great view of the Korean team coming into the stadium.

"What an entrance by the unified Korean team. The whole stadium stood up to greet them, and they continued to wave their mini torches as the team made its way around."

Have a look here to see some of the best pictures from the opening ceremony so far.

That is all of the nations into the arena, almost pretty much bang on time. We will have some speeches at 12:30 GMT ish and the lighting of the flame about 30 minutes after that. Stay tuned.

There is nothing like sport to bring countries and nations together. The athletes perform from the heart. We were told people in the audience were sobbing waiting to see this moment happen. It's incredibly inspiring.

The biggest cheer of the night comes for the last team of the night. And it is a great sight as a united Korea team, walking in under the flag of a united korea, comes in together.

The flag is held by two people - Hwang Chung-gum of North Korea and Won yunjong of South Korea, with South Korea president Moon Jae-in watching on.

Here are how the Kazakhstan, Chile, Czech Republic and Georgia teams looked.
