A musical group claims to have "gatecrashed" Buckingham Palace, fooling guests at a private art talk.
In a video uploaded online, Cat's Eyes said they had attempted to get into the palace last month to perform a song from their new album.
The duo, comprising opera soprano Rachel Zeffira and Faris Badwan, who sings with British psychedelic rockers The Horrors, claim to have performed at a private art talk.
The footage begins outside the palace with a phone call playing over the top from someone mentioning band member Rachel Zeffira, and asking for email correspondence "because there were a couple of things that we weren't aware of regarding the musicians and we just wanted to follow this up".
This is followed by blurry, shaky footage, tagged as "Faris Spy Cam", appearing to show someone passing through security.
The group said they pretended to be a Renaissance ensemble performing music from that era, when really they gave a live rendition of their own song, "We'll be Waiting".
The footage shows seven musicians dressed in black performing with a conductor while guests stand and watch in what is understood to be the Queen's Gallery, a building adjacent to and separate from Buckingham Palace, run by the Royal Collection Trust.
It is reported Ms Zeffira's name was on the guest list and she had been able to add some friends when she helped provide a speaker for an after-dinner talk on the Palace's art collection.
The Times reported Ms Zeffira to have said: "I can't outright admit that I committed a crime but I did have to lie to make it happen."
