Dublin Fire Brigade also shared a pun-tastic tweet before the gig inspired by Buble-isms.

They wrote: "YOU CAN NEVER TELL, WHERE OR WHEN a fire will break out in your HOME. IT HAD BETTER not BE TONIGHT. If you feel you are SWAYing stay away from the cooker. Before you CLOSE YOUR EYES, close your doors. And hopefully in the morning we HAVEN'T MET YOU YET #michaelbuble #DrunkCooking"

It was Buble's first performance after two years away from the limelight as his eldest son Noah, 4, fought liver cancer.

Ahead of his Dublin date, Buble told how he is “grateful” for the best wishes of fans as his son battled cancer and said: “It kept us alive, it kept us going through.”

But the Canadian superstar — who admits he has “been to hell” — added: “We are not the only family that’s gone through something like this and there’s many families.”

Speaking about his lad’s battle, Michael told the Irish Sun he wants to “thank all of those people who sent their prayers, who sent their well wishes, who hurt for us”.

He said: “We were more than grateful for that love that we got, it kept us many days. It’s hard for me not to get emotional.”
