Michael Bubléwas busy promoting his ninth album,Nobody But Me, when he found out about hisson Noah’s cancer diagnosis.

In October 2016, just minutes before he was scheduled to perform in London atThe One Showon BBC One, the 42-year-old singer got a text message from his wife,Luisana Lopilato.

“Three minutes before I came on,my wife texted and told me something was wrong,” he said during an interview with U.K. publicationEvening Standard, adding that she attached an image of their boy’s surgical scan.

“I just died,” Bublé, who stayed for the performance despite his mind being at home with his family, recalls.

“I don’t know how I even sang, man, I just did it on autopilot,” he explains, adding that his decision to sing his cover of The Beach Boys’ “God Only Knows” — which was featured on the album — was especially emotional.

“The worst part was I was singing a song I had recorded with my kids in mind — ‘God only knows what I’d be without you…’ ” he says.

Immediately following the show, Bublé hopped on a private plane to go back to Los Angeles to be with his family, where he spent the next seven months with his son, now 4½, in the hospital.

In spring 2017, Noah finally came home from the hospital — and luckily now, 21 months after his diagnosis, Noah is continuing to recover.

“He’s perfect,” Bublé tellsEvening Standard. “Clinically speaking, it was a tumor within the liver. And the most important thing was to get it out, with clean margins. Because if you do, it goes from being this scary thing to just being tremendous odds.”

“No one likes talking about percentages but, honestly, [we have] a percentage where we can live our life, and not live in fear every day. We know we’re OK now. But what we went through was f—ing brutal,” he adds.
