There’s a second part to the great story of the Shetland salt fish trade – this is the inspiration that it has given many artists, novelists, poets, film makers and musicians. A great Scottish poet went fishing for herring in Shetland, and a famous Faroese artist painted the fishermen of his home village at work.

The story also includes a lost fiddle tune, played by distant-water cod fishermen, and reinvented in recent years. John Goodlad in conversation with Spencer Rosie explores the art and the music, and Three in a Bar play some of the tunes, with his new book launched along the way.
