BBC News By James Cook Published Sweet sounds are tripping down a potholed lane in Glasgow's wealthy west end. It is the music of the clarsach, the old Gaelic harp, which ripples over the air and down the ages. From Viking raids and Wars of Independence, to Union and Enlightenment, Empire and oil, Scotland has sung many songs. Now, says Sophie Rocks, leader of clarsach group The Willow Trio who are rehearsing in a garage studio, it's time for a new tune. She reckons the "divide between Scotland and England," is more prominent now than when she, and a majority of her fellow Scots, opposed independence in 2014.
