Two members of one of the biggest boy bands were filmed practising backstage together before their Norfolk gig at the weekend.

Take That stars Mark Owen and Robbie Williams were filmed singing Greatest Day backstage before Williams' performance at Sandringham Estate on Sunday night (August 27).

Williams' former bandmate Owen was the special guest ahead of the star's headline set, and his wife Ayda caught the moment on film.

Posting on Instagram, Mrs Williams commented on the post: "Backstage Highlight: Watching Robbie Williams and Mark Owen together always fills the room with a special kind of love.#brotherhood #takethat #backstage AW xx"

It was Sandringham's first large-scale concert series, organised by Heritage Live, and Williams was on the line up alongside Van Morrison on Friday and The Who on Monday.

Our reviewer, Louisa Baldwin, gave the gig five stars. She said: "Robbie Williams gave a performance fit for a king and treated fans to a non-stop stream of hits on his first night at the royal Sandringham Estate.

"It didn't disappoint and the ultimate showman proved he is still top of his game."
