Watch Coldstream Guards belt out 'Three Lions' ahead of England Denmark semi-final

Watch: Three Lions played at Clarence House at Prince Charles’s request

Prince Charles wished the England squad the best of luck as he requested two football anthems to be played by a royal band ahead of the Euros semi-final on Wednesday evening.

Charles, 72, asked the Coldstream Guards to play Three Lions and Sweet Caroline outside Clarence House, his official London residence, to show support for Gareth Southgate's men.

The prince and his wife Camilla, the Duchess of Cornwall, are in Wales on their annual week of engagements there, but are said to be following the tournament, despite the Welsh team being knocked out by Denmark in the round of 16.

Sharing the video, Charles and Camilla added: "Best of luck to the #ThreeLions

in your semi-final Euros match tonight!"

A royal source told PA of the England match: "Both Their Royal Highnesses [Charles and Camilla] will be closely following the outcome."

The soldiers wore their bright red tunics and bearskin hats as they stood in the sunshine in the royal courtyard, and played the tunes which have been sung by England fans over the last few weeks.

Charles' son William will be attending the match at Wembley on Wednesday evening, which kicks off at 8pm.

He took his wife Kate and his son Prince George to the match against Germany, but Kate is now self-isolating after being told she had been in close contact with someone who later tested positive for COVID-19.

It rules her out of going with her husband, but it's not known if George would go along with his dad.

Three Lions was written by David Baddiel and Frank Skinner with the Lightning Seeds in 1996, when England got to the semi-final of a major tournament.

Sweet Caroline by Neil Diamond has become a sporting anthem, first picked up by cricket and darts fans before football fans took it on too. Fans of William's team, Aston Villa, have been singing it since 2019, and the players sang it in the locker room after their promotion that year.

Manager Southgate said the fans' singing was "incredible" and added: "To hear them at the end… I mean, you can’t beat a bit of Sweet Caroline, can you? That’s a belter, really."

If England beat Denmark at Wembley on Wednesday it will be the first time they make it into the final of a major competition since 1966, when they won the World Cup.

The match kicks off at 8pm.
