While the Welsh watch their sheep (or their neighbours') peacefully grazing, the Irish sail off around (their) sea, stopping at various congenial watering holes for a bit of a sunbathe. Arriving on the coast of 'Cumbria' (taken rather broadly--I imagine to have a quickie marriage at Gretna Green or to do some shopping at The Lanes in Carlisle), they decide they like it and begin debating whether to call it a "holiday home" or "the first step in the great Irish Empire".
Interestingly enough, the King of Scotland happens to be in the area, on a holiday of his own with a few thousand close friends and retainers. It will be interesting to see how he reacts to the Irish dilemma.
