In 2009 he was a special guest in the BBC Cardiff Singer of the World competition, broadcast on 11 June on BBC Two (Wales only).
Jones auditioned for Star Wars: The Force Awakens (2015) but did not get the part. However, he was later offered the part of Captain Canady for the sequel, Star Wars: The Last Jedi. He appears prominently in the opening sequences and says he played the part with "a posh Welsh accent".
