I was also delighted that Neil mentioned "I Vow To Thee, My Country"
I'm happy to have brightened your day, Mr D. Holst's personal dislike for the tubthumping you mention didn't prevent him producing an inspiring melody now and again :-)
In the same way that Elgar, if I recall correctly, found it increasingly irksome that Pomp and Circumstance No.1 should always be associated with "Land of Hope and Glory". Although since Elgar had written so much that was directly associated with "Imperial grandeur" one has less sympathy with him than for Holst who was not so associated.
