London 2012: Wales' choir role at opening ceremony
A children's choir will represent Wales during the opening ceremony of the Olympic Games on 27 July.
Only Kids Aloud were filmed singing Cwm Rhondda at Rhossili beach on the Gower and the video will be played at the ceremony.
The 80-strong group has been put together from all over Wales through the Wales Millennium Centre.
Other choirs have recorded songs for England, Scotland and Northern Ireland respectively.
Craig Yates, who sings with one of Wales' leading choirs Only Men Aloud, conducted the youngsters at the beach.
"It was a real privilege to be asked," he said. "I've never done anything like this before.
"I've been working with them for a few months now and we got together last week to record the track.
"This is a great place to show around the world and these kids have got so much talent that the world deserves to see them."
Mr Yates said Cwm Rhondda was the "perfect choice" as it is the "unofficial national anthem of Wales".
Producer Rhian Williams has been behind the project said she was only given a small amount of time to shoot the film.
"It came to us very, very late in the day, about a week's notice to shoot a choir of 80 on the beach which as you can imagine is quite a feat in itself.
"We had to get going at it very, very quickly because to get a body of 80 children who don't belong to a school or a specific choir is quite a task to get all the authorities contacted, get them on board, let alone doing the creative side.
"The children have taken it on board from the word go. They've been wonderful and we've worked with the Wales Millennium Centre to make this happen.
"The request went to them to find a choir to represent Wales and what better can you ask for than Only Kids Aloud."
A choir from Scotland will sing Flower of Scotland, one from England will perform Jerusalem while a choir from Northern Ireland is singing Danny Boy.
