Michael Buble Lets 15-Year-Old Boy Sing Onstage

Back in 2010, Michael Buble let a boy sing onstage and gets a very pleasant surprise!

On ITV's An Audience with Michael Buble, the Canadian crooner is told by a mother in the audience that her 15-year-old son Sam is a great singer too.

Buble invites Sam onstage to sing Nina Simone's I'm Feeling Good... And Sam proves his mother right!

'I've got another four years before Sam wins the X Factor and drives my career into the pavement,' jokes the It's A Beautiful Day singer.

Michael Buble is playing ten shows at London's O2 Arena this summer. Maybe there will be more moments like this?
