The singer was also joined on stage by his Take That bandmates, before Robbie came back for a rousing rendition of Never Forget.
Prince Charles, in a video message recorded before he embarked on his tour of Australia, New Zealand and Papua New Guinea, commended Barlow on his charitable work.

Not only for my Prince's Trust and the Queen's Diamond Jubilee, but also for Comic Relief, Children In Need and many more.
Over the past 25 years, you have become one of the great stars of the British music industry and you are the very embodiment of that rare species, 'a national treasure'.
Presenting the award, Sir Elton John said Barlow was a "thoroughly fine human being" who had come through bad times without any bitterness.
Sir Elton joked: "If you were gay I'd marry you."
The Take That star said he was "delighted and humbled" to accept the award.
– Gary Barlow
I've been doing this for 22 years now, and the one thing that's more apparent to me than ever before is how much I love performing.
To be able to do it, I feel really lucky, I never want to turn my back on it. It's so special when you get something like this, because it's recognised within the industry.
I'm a lover of this industry, I'd do anything to protect it, and when you're given something from that industry, I'm honoured.
Barlow, who penned a song with Andrew Lloyd Webber for the Queen's Diamond Jubilee, was joined at the event by his Take That bandmates and fellow X Factor judges Nicole Scherzinger, Tulisa Contostavlos and Louis Walsh.
Other stars in attendance included Kimberley Walsh, Alesha Dixon, Mylene Klass, Jason Donovan, Chris Moyles, Dermot O'Leary and Donny Osmond.
Previous winners of the award, which raised funds for Nordoff Robbins and The BRIT Performing Arts & Technology School, include Sir Elton and Kylie Minogue.
