The Welsh folk singer Lleuwen Steffan was working in a museum archive when she came across recordings of Welsh-language hymns she had never heard before…. Many of the hymns date back to the 18th century and passed down through the generations. Steffan said: “They’re conversational and the lyrics feel so current. There were committees who would choose what hymns would go into the hymn books. These were the unchosen ones, the cancelled ones, if you like.
