Prince Harry and Meghan Markle get emotional at Sydney memorial as Princess Diana's song is sung

Day five of Prince Harry and Meghan Markle’s jam-packed autumn tour proved to be a bit of a rollercoaster, both emotionally and physically. Ahead of the Duke and Duchess of Sussex kicking-off the 2018 Invictus Games, a full-circle instance for the lovebirds who made their public debut at the sporting event last year, they exhausted a more somber engagement.

The newlyweds attended the official opening of ANZAC Memorial in Hyde Park, which aimed to honor all Australians and New Zealanders who have served and lost their lives in service of their country. The poignant outing seemed to hit even closer to home for Harry when a certain hymn was sung.

Both the 34-year-old prince and his 37-year-old wife could not hide their emotions, wiping their eyes throughout the melancholy occasion. As fallen servicemen were remembered, the royal’s heartstrings were tugged at. Harry especially looked touched, which is no surprise as he has served himself and since then dedicated a lot of time to assisting men and women in the armed forces. 

Maximizing their emotional states was the fact that the event’s choir sang I vow to thee my country, one of Princess Diana’s favorite hymns from her schooldays, according to PEOPLE. The song was notably performed at the Harry's late mother's 1981 wedding and 1997 funeral.

Meghan continued to hit her royal tour style mark, looking the portrait of elegance in a black, white-button on dress by New Zealand designer Emilia Wickstead, a clear nod to the service’s mission.
