LONDON - Brit army’s world-famous Band of the Coldstream Guards left hordes of tourist stunned after they started playing Michael Jackson’s mega hit ‘Thriller’, and even marched to its tune on Wednesday.

As many as 40 drummers, trumpeters, clarinet, and trombone players played out the song, with the band marching in formations almost mimicking the famous choreographed zombie routine from the music video.

“It came out of nowhere,” the Sun quoted Philip Marfleet, 22, a lighting engineer, from Colchester, Essex, as saying.

“We were stunned. They were practising some more traditional tunes and then all of a sudden they started playing Thriller.

“What a moment,” he added.

Marfleet, who managed to capture the show on his mobile phone, had gathered with more than 20 foreign tourists outside The Guards Museum, in Birdcage Walk, central London to enjoy the spectacle.

“It obviously wasn’t the first time they had played it. It was a polished performance,” he said.

“A few foreign tourists asked me what it was all about, but I was unable to give them an explanation. I was as stunned as they were.

“At one point the musicians even appeared to be putting together some moves to go with the music.

“Instead of marching in straight lines they formed a triangle,” he added.

The oldest and best known band in the Army, based at the capital’s Wellington Barracks, have actually been doing the routine for the last two months.

“The piece has been part of their summer repertoire for a number of events and they’ve been playing it publicly for the last eight weeks, including at the Windsor Tattoo,” a MoD spokesman said.

“It is just a coincidence and not a tribute to Jackson,” he added. (ANI)
