You can't beat Land of Hope and Glory (Pomp and Circumstance by Elgar of course). Even as an Irishman, my heart swells when the big runup to the chorus, as it were, winds up. I remember I was playing a classical selection many years ago, and had the speaker at the window. Then Elgar came on. Being in a fiercely Irish nationalist estate, I had to suddenly turn it way down before the rocks started flying at my window!
Another great classic English song is "Fantasia on Greensleeves" by Ralph Vaughan Williams. Love that.
