However, while Bublé enjoyed singing to huge crowd to mark the opening of the stadium, he knows he fans to prefer to come and see him in a “more intimate’ setting.

Speaking about his five-night run at the O2 arena the Beautiful Day singer said: “I know this is a big venue, but it has much more of a theatre feel. And the sound in here is just amazing.”
