Gary Barlow has revealed the Queen's Jubilee concert is to echo celebrations of a decade ago with another performance from the roof of Buckingham Palace.
Queen guitarist Brian May notably played above the venue in 2002 to mark the Golden Jubilee, a moment which became one of the lasting memories of the celebration.
Now Gary says there will be a further rooftop appearance at the event he has been planning for June 4, although he's keeping tight-lipped about the identity of the performer.
The show is due to feature stars such as Sir Paul McCartney, Will.i.am and Sir Tom Jones. Robbie Williams is also on the bill and he has previously been known for daredevil performances in his shows.
The event is taking place in front of the palace to crowds gathered around the area of the Mall and will see colourful projections beamed on to the Palace.
Take That star Gary said: "You've certainly never seen Buckingham Palace look like it's going to look on the 4th of June before. We're doing lots of projection onto the palace, from 9.15, but up until then we've got the most famous historic building in the world as our backdrop. We've got fireworks, we've got someone performing on the roof. It's going to be an amazing night."
Asked who would provide the rooftop slot, he responded: "I can't tell you."
Brian May famously performed a guitar version of God Save The Queen during his Palace show, part of a concert in the grounds.
But aside from the rooftop slot, Gary said he was keen to ensure it was very different to the celebration for the 50th anniversary of the Queen's ascent.
He added: "It's going to be good because of all the effort that everybody's put into it and it will feel different."
