WATCH: Michael Bublé Makes Emotional Return To Stage

Michael Bublé got emotional Sunday as he performed in a downpour in London’s Hyde Park.

Singing “Always on my Mind,” the B.C.-born crooner fought back tears.

Bublé also took time out to thank fans for their support in the wake of his son Noah’s cancer diagnosis two years ago.

“It’s been two years since I’ve been on stage, and like any human of course I worry that whatever I had at one point might have gone,” he shared. “But after two songs, I’m even better than before.

“There are no words for how much love, affection, gratitude, that I have in my heart on behalf of myself, my family, for your love, for your prayers, for your support.”

Bublé, who stepped away from the spotlight inn 2016 to focus on caring for Noah, thanked fans for “everything you’ve done for me.”

During his London concert, Bublé brought Noah out on stage.

The singer and his wife Luisana Lopilato also have son Elias and are expecting their first daughter next month.
