Welsh chorus Only Kids Aloud will rehearse for the final time today before heading out to Cape Town in South Africa.
It's part of the country's year-long celebrations to commemorate 20 years of democracy in the country.
Sir Emyr Jones Parry, Chairman of the Wales Millennium Centre, says Wales' involvement in the celebrations will ensure the next generation will never forget.
Wales was prominent in the campaign against apartheid and it is only fitting that Wales' national centre for the performing arts should participate in the year-long cultural celebration '20 Years of Freedom - South Africa 1994-2014.'
By involving our children's chorus in these celebrations we are also ensuring that the next generation will never forget the immense sacrifices that were made for democratic freedom in South Africa.
