He may have just released his new solo album 'The Heavy Entertainment Show' last Friday, but Robbie Williams is not averse to a bit of good old-fashioned nostalgia from time to time.

The star was playing a special one-off gig at London's Troxy venue last night to celebrate his BRIT Icon award, and fans were left gobsmacked when he unexpectedly brought his three Take That bandmates on to the stage.

Williams last played with Take That during the album recording and tour cycle of their 2010 album 'Progress', which ended in 2012. Last night was the first time he has performed with the band without Jason Orange, who left in 2014.

It was only right, of course, that they perform their pop classic 'Back for Good', as well as 'The Flood', while fans were reduced to tears when Mark Owen told his bandmate: 'Robbie, you will always be a member of Take That'.
