Hamish MacCunn ( 1868-1916) was a romantic composer, pianist and conductor who lived in Thornhill, Ardgowan Street, Greenock. He was the second son of a merchant and shipbuilder and went to the old Greenock Academy. He has been described as the "most Scottish of Scottish composers", wrote many orchestral and choral works and was quite famous in his day. Probably his best known work is the magnificent, "Land of the Mountain and the Flood" overture which was used in the 1970s as the theme tune to the television series, "Sutherland's Law". This was an amazing achievement as it was completed when MacCunn was only eighteen! It can be heard here.
