Canadian chart-topper Michael Bublé made an emotional return to the stage last night (July 13) after a two-year absence.

Bublé was performing at Barclaycard presents British Summer Time in London's Hyde Park, reportedly his first show since his four-year-old son Noah's cancer diagnosis.

Fighting back tears, Bublé told the crowd: "Two years since I've been on stage! And, like any human being, of course, I worried that maybe ... my voice wouldn't hold up," his voice cracking.

But after the crowd let out a cheer, a re-energised Bublé gathers himself and says: "After two songs, I'm better than I was before!"

He also makes a joke about the UK dating reality TV show "Love Island."

As the British Simmer Time concert in Hyde Park, Michael Bublé talks to the audience, regarding the fact that this is his return to the stage after a two-year break. It's raining heavily, but Bublé braves the weather to come and talk to the crowds.

He mentions his worries about not being up to it any more and begins to get emotional. The crowd obviously disagrees. He makes some jokes and then talks about how the concert is a lot like Love Island.
