“In the film we think we’re going really fast, and then you cut to us and it’s just pathetic – ducks could’ve gone past us,” said Speirs.
The show is part of a series of programmes that celebrate the history, culture and people of Merthyr Tydfil – the world’s first industrial town – as Cyfarthfa Castle celebrates its 200th birthday.
Speirs said the idea of the show was for him to show “a great friend that I love very much around Merthyr”.
“I couldn’t get hold of him, so Ruth came,” he joked.
Jones said she knew a little bit about Merthyr before making the show because her sister worked there as a doctor, but what surprised her the most was how green it was.
“We met so many people who had set up different business – it was a very proactive place,” she said.
Jones also said she would like to reciprocate Speirs’ hospitality and show him around her hometown of Porthcawl, Bridgend.
“I would really love him to see it,” she said.
