The choir, which has performed all over the world, has also moved with the times making recordings of football anthems and Bob Marley classics alongside the more traditional Welsh choralmusic of its origins.
The 63-year-old, who trained as what is now the Royal Welsh College of Music and Drama in Cardiff has taught instrumental music and choral proficiency to children and adults for 40 years or so.
The project aims to transform society through music, reflecting the idea that orchestral and choral practice gives children and youth important values and helps preserve them from the dangers of drugs and crime.
