Twitter went right into a frenzy with many satisfied that his putting look of huge shades, gray hair and a powerful moustache was a cover-up.
He was in comparison with former US president Donald Trump whereas others quipped it was the truth is Meghan in costume.
In a tweet @NickdeSemlyen wrote: “I refuse to imagine that this isn’t one of many Beastie Boys.”
One other (@WayneTechSPFX) stated: “Mysterious man on the coronation solved. It is Trump.”
However others had been fast to leap on the “insane” theories spiralling on-line.
One consumer did not perceive how a 79-year-old man could possibly be in comparison with a 41-year-old lady and the Royal Academy of Music tweeted to say it was “very proud to dispel” rumours.
