Dafydd Iwan's 'Yma o Hyd' will be belted out loud and proud at Cardiff City Stadium as Wales take on Ukraine for a place at the World Cup later this year.
It has become a popular pre-match tradition to have the song about the survival of Welsh culture and language sung before the national team play their matches in the capital.
Iwan is set to attend and perform on Sunday, June 5, after his tune was adopted by Rob Page and his players - as well as Wales Women - having previously been sung at Scarlets rugby matches and at Wrexham AFC games. Connor Roberts and Chris Gunter are big fans of the song, with Page revealing earlier this year it was the latter who played a big part in its introduction to the Welsh national team set-up. Page said: "Yma o Hyd, that's a massive anthem for us now. Chris Gunter started it. We played it everyday before training and on the coach, and that's something we've got now as our anthem. It's a big part of what we're all about. The song is very poignant to what we're all about. We can all relate to it. We're all passionate Welsh people who love our country."
