‘Shallow Brown’ (Roud 2621) is a fascinating song for so many reasons. Is it a sea shanty? A slave song? Who is singing to who, and where in the world were they singing? There’s as much here to love as there is to be heart-broken by. Quite simply, another traditional folk song of fare-thee-wells and loved ones being transported over the sea that feels, in some ways, as prescient now as it ever must have done.
