Gary Barlow’s performance of Sing at the Classic Brits will feature an accompaniment from the group, Military Wives, reports The Metro.

Sing, the single that made Prince Harry the first royal to top the charts, is up for the Classical Brit Awards ‘single of the year award’ after shooting to number one in the singles chart, while the album of the same name took the top spot in the albums chart. The successful choir group Military Wives will perform the song, whilst Barlow and Andrew Lloyd Webber - the composers of the single for the Queen’s Diamond Jubilee celebrations - will appear on stage at the awards show playing grand pianos. “The Classic Brits is something I’ve never done before, so I’m very excited to be a part of it,” explained Barlow. “It’ll be nice to get everyone back together for a performance of Sing as we’ve only ever performed it once together live.”

In My Dreams – the first studio album from Military Wives - topped the charts and got them into the top ten of the Classic FM Hall Of Fame. Opera singer Russell Watson will also be performing at the event after having to cancel his appearance at the event last year due to health problems.
