Sir Elton John will perform for Queen Elizabeth II at her upcoming Diamond Jubilee concert alongside Sir Paul McCartney, Dame Shirley Bassey and Sir Cliff Richard.
The British monarch marked 60 years on the throne on Monday (06Feb12) and a star-studded show is being organised for this summer (Jun12) as part of the festivities.
The line-up for the event at London's Buckingham Palace was officially announced on Tuesday (07Feb12), and the cream of the U.K. music industry will take part, including former Eurythmics star Annie Lennox, Jools Holland, Sir Tom Jones, pop group Madness, boyband JLS and singers Jessie J and Ed Sheeran.
Other acts are set to be unveiled in the coming weeks and Take That star Gary Barlow, who is helping to organise the show, reveals he's still looking to sign up a number of big international names - especially those requested by The Queen's grandsons, Princes William and Harry.
He tells the Bbc, "They've asked for a couple of artists, which I'm still running round the world trying to get hold of! But they're quite involved musically, so we're hoping to pull it off for them.
"I don't just want to represent the Commonwealth up there, I want the whole world to be on that stage as the whole world will be watching that stage that night. This is gonna be a massive event on a worldwide basis so I'm very excited. 2012, I hope, will be remembered forever for this concert.
"I want to focus on the U.S. in the next month and try and get some U.S. artists on the bill also... I think artists are so honoured to be involved in this show. Interestingly, internationally the love for The Queen is amazing and the fact that people want to be involved so heavily in this concert has been incredible, it makes my job much easier!"
The Diamond Jubilee Concert will take place on 4 June (12).
