A man who served as a Grenadier Guard at Queen Elizabeth II's coronation 70 years ago is dishing out advice for the guards who will be serving at King Charles III's coronation on Saturday, May 6.

Roy Blake, 89, was in the Grenadier Guards for three years after he turned 18 in 1952, news agency SWNS reported.

"The Grenadier Guards are one of the most senior infantry regiments in the British Army," according to the British Army's website. 

They are known for wearing a uniform of scarlet tunic and tall bearskin hat.

In addition to "providing excellence, symmetry and precision while carrying out ceremonial duties in London and at Windsor Castle," the Grenadier Guards "specialize in Light Role Infantry operations," the British Army's site also says.

After much training as a Grenadier Guard, Blake stood for hours on the streets of London, guarding the mall outside St. James Park during Queen Elizabeth's coronation in 1953, said SWNS.

The weather that day was not great, Blake recounted to SWNS — but still, he relished the experience. 

"Apart from the fact [that] it rained for nine hours and we got completely wet … it was fantastic," he said.

In particular, Blake said that "the public really made the atmosphere at the Queen's coronation."

King Charles III has "big shoes to fill."

He added, "It was almost hysterical in some ways because they really made a festival of it."

"I think it will be a different kind of ceremony altogether," he told SWNS. 

"I'm not too excited because I've been there, done that, got the T-shirt." 

He also remarked that, to him, "it doesn't seem long since the Queen's coronation."
