Jon Bon Jovi, Taylor Swift & Prince William

You may live to be 100 and never see a video like this again – Jon Bon Jovi, Taylor Swift and Prince William of England singing “Living On A Prayer.”

The once in a lifetime performance happened Tuesday evening during the Winter Whites Gala charity event at Kensington Palace, according to the BBC.  The benefit was for the Centrepoint organization which helps the homeless.

Prince William, otherwise known as the Duke Of Cambridge, presented the Centrepoint Great Britain Youth Inspiration Award to Bon Jovi for the rocker’s humanitarian work.

In addition to Swift appearing at the event, James Blunt and Tinie Tempah were in attendance as was actor Benedict Cumberbatch.

“This is my first time playing at Kensington Palace or any palace for that matter,” Swift said.
