Jessie J, JLS and Shirley Bassey are also set to perform, according to reports
The tabloid also reports that it took a long time for Barlow to persuade McCartney to perform at the event, with a source telling the paper of Barlow’s plea to the Beatles man: “He laid it on thick, telling him he was the only man for the job”.
The concert is set to take place this summer and will be broadcast live on the BBC as part of four days of celebrations for the Diamond Jubilee. Barlow has also tweeted that he will announce full details of the concert during an appearance on The One Show tonight (February 7).
He wrote on Twitter.com/GBarlowOfficial: “Remember to watch the One Show tomorrow night. We’ll be live from Buckingham Palace, announcing plans for the Diamond Jubilee.”
