The photographer shoved down Pall Mall by a military parade says the mishap didn't spoil his big day out - even after the embarrassing footage was uploaded to the internet and viewed by millions of people.
Gerry Weatherhead, 58, was clattered 15 yards down the road when he strayed into the path of a group of marching Grenadier Guards.
The troops were marching through Admiralty Arch and up The Mall when Mr Weatherhead was wrenched from his wife’s grip and swept into the procession. He was manhandled by the soldiers some distance as they headed towards the palace.
Photographer Mr Weatherhead, 58, had been visiting London for Saturday’s annual Trooping the Colour display.
"I was handing the camera to my wife so I could go to the gents' and, next minute, wallop!" he told the Standard today.
"I should have known what was happening, but there was so much noise.
"Every now and again there was a bunch of soldiers walking past and I just didn't hear them coming.
"I was just shoved forward and carried on going until I pushed my way to one side. It was a little bit embarrassing, but nobody was hurt.
“It won’t happen twice."
Mr Weatherhead said he had hoped to keep his run-in with the Guard a secret - but realised his efforts had been in vain when a friend posted the video on his Facebook wall.
By Wednesday morning the YouTube clip had been featured on a number of news websites and millions of people had seen it.
The video shows him speaking to wife Ros as the regiment mows into him. As he disappears off screen, he is shown being shoved between the soldiers like a pinball.
"I don't know what would have happened if I had fallen or if there was an elderly person there," he said. "In my day there was always someone at the front shouting 'make way'.
"I was just shoved forward and carried on going until I pushed my way to one side."
Mr Weatherhead said watching the celebration, which marks the monarch's official birthday, was something of a lifelong ambition.
"It's something I always watched on TV, so I grew up with it," he said. "I always wanted to go and see it.
"We'd never managed it, although we do go to London, so this was the first time I've been down there. So much happened in one day.
"I got some really good shots of the Royal family. We had a great day and that didn't spoil it.
Asked what he would take away from his 15 minutes of fame, he said: "Keep one eye open."
