Chosen by The Duke of Edinburgh himself, “I Vow to Thee, My Country” was the first song played at Prince Philips funeral procession. The song is representative of the Dukes lengthy and undivided loyalty and love for his country. The placement of the song, also chosen by The Duke, being the first one played, is even more poignant.
