Michael Buble's incredibly emotional performance following his son's cancer diagnosis

Viewers of the Children in Need live appeal were left in tears after Michael Buble's heart-breaking performance of God Only Knows, just weeks after it was confirmed that his son Noah, three, was battling cancer.

The couple released a statement saying they would be “putting their careers on hold” while Noah received treatment, with Buble reportedly vowing to not sing again until his son had beaten the disease.

However, Buble made one last appearance on the televised charity fundraiser, performing a rendition of the Beach Boys' hit, God Only Knows. 

You can see the heart behind Buble's performance and you can even hear the passion in his voice.

The 41 year-old recorded the song for the children's charity back in October, before his son was diagnosed with cancer.
