I'm agreed that Britain is not a country, it's an island containing a number of countries. But as for England, I think it's high time we got back to the little countries of the Heptarchy.

But "the thinking behind it" in referance to a tune? I'm bewildered by what that can mean, more especially in relation to the one used for Jerusalem, which is tranquil and encouraging rather then in any way boastful. Now, the tune of Land of Hope and Glory, maybe that does match it's title, "Pomp and Circumstance" - though in fact Elgar didn't write it with the words of Ho eand Glory in mind, and he loathed having it used for them.
