Michael Bublé: Meant to be onstage

Michael Bublé emulates Tony Bennett. But there's one bit of advice the legendary singer offered him he just can't follow: be a little nervous before every show. That's because Bublé says he's more comfortable on stage than off, he tells Lara Logan, in a "60 Minutes" profile to be broadcast Sunday, Dec. 4 at 7 p.m. ET/PT.

"I remember talking to Tony Bennett...and he said 'Be a little nervous before every show.' And I thought...I'm toast because I just didn't have that," he says. "I was so comfortable up there...I'm more comfortable there than I am in a room. It's...my personality, who I am, I was meant to be up there," he tells Logan.

Logan spent time with Bublé before a show backstage, with his family in the town where he grew up and with his wife, Luisana Lopilato. Logan also brought cameras to shoot Bublé in the studio recording his current album of holiday classics, "Christmas."

Bublé fills concert halls and has sold 35 million albums by covering classic songs from the American song book made famous by Bennett and his old friends like Frank Sinatra and Dean Martin. But he covers pop music and rock and sings his own songs, too, making him hard to pin down musically. "It's one of things where it's hard, who am I?" he says, acknowledging that the music industry hasn't quite accepted him despite his success.

"It turns out that I'm far too schizophrenic musically for people to categorize me," says Bublé.

There's one category his singing falls neatly into: sales. Bublé's "Christmas," released only a few weeks ago, is already the number-one selling album in the country.
