The Coldstream Guards do K-pop outside Buckingham Palace

The Coldstream Guards Band, typically steeped in tradition, surprised spectators by harmonizing to the beats of contemporary K-pop tunes on Wednesday afternoon.

Onlookers were treated to a rendition of 'DDU-DU DDU-DU' - one of Blackpink's most famous tracks, as well as the global mega-hit 'Gangnam Style' by Psy.

The performance was in honour of the South Korean state visit after the Royal family hosted the President and First Lady at Buckingham Palace the night before.

Meanwhile, the "Army In London" captioned the performance as "You’ve not heard anything like this before!"
