In the middle of one of Bublé’s most well-liked live performances in 2010, a woman in the audience interrupted.

After engaging in a fun chat, Bublé finds out that Sam, the woman’s son, is a talented vocalist who wants to be just like Bublé.

Buble invites Sam, who is now feeling quite uneasy, to come up on stage and plays along with him.
