Gary Barlow and his Commonwealth Band have leapt to the top of the singles chart this week with his Jubilee anthem Sing.
He also held on to the number one spot on the album chart to make it a double for the Take That star.
The Official Charts Company said the Diamond Jubilee song, co-written with Andrew Lloyd Webber, made 142,000 sales since last weekend's Jubilee concert, to become the biggest selling number one of the year so far.
Gary masterminded the show in front of Buckingham Palace and was joined on stage by many of the artists who recorded the track, including the Military Wives choir and the African Children's Choir with their soloist Lydia.
The single - which was at 11 last week - also features Prince Harry bashing a tambourine, making him the first British royal to perform on a number one single.
Gary said: "It's been such a great week, it would take something very special to top it. I'd like to say thanks on behalf of about 200 people, as we've got a massive cast on this record.
"I love collaborating with other artists and being able to put them all on one stage, the other night was such an honour for me. It's something I'll never forget."
In second spot was Whistle by Flo Rida, a new entry, and in third place was last week's number two We Are Young by Fun, featuring Janelle Monae.
Last Sunday's number one Feel The Love by Rudimental, featuring John Newman, dropped to four, while Usher's Scream was a new entry at number five.
Singer songwriter Ed Sheeran's award-winning + flew back up the album chart from 13 to two this week, and fashion icon Paloma Faith's Fall To Grace slipped from two to three.
