We have heard Dafydd Iwan's songs for over half a century. We are so familiar with the words and melodies. They are part of the fabric of being Welsh. Yet, there is always something new to learn about each song.

Rydyn ni wedi clywed rhai o ganeuon Dafydd Iwan ers dros hanner canrif. Mae'r geiriau a'r alawon mor gyfarwydd. Maent yn rhan o fywyd pob Cymro gwerth ei halen. Eto, mae rhywbeth newydd i'w ddysgu am bob cân.
