Michael Bublé kicked off the publicity campaign for his illustrated memoir, On Stage, Off Stage, last week. A red carpet was rolled out at Waterstone's Piccadilly for the crooner, where 400 people had camped out to get their book signed and a two-storey high projection of the cover was to be seen on the front of the store.

Michael also made an appearance at Tesco head office, charming staff and even giving an impromptu performance.

Jonathan Ross had Michael on his sofa on Saturday and interviews are still to come on This Morning, BBC Breakfast, Magic, Heart and plenty of print interviews too.
