Well done Masato!                                                

Loch Goil is a sea loch (fjord) off of the Firth of (river) Clyde. All of the place names mentioned are in the Firth or the Irish Sea, especially Ailsa Craig ("Paddy's Milestone"). Cloch ("stony") Lighthouse is visible from my front door and Toward Point is about eight miles south.

The tune and basic structure is "Greenland Whale Fisheries". I wonder which came first?
