When you think of an artist like Michael Bublé you have pretty much come to the terms that the only place you are gonna hear this guy is live in concert, on a TV show, on the radio or on the internet.  However, a group of commuters in a New York subway were surprised with an performance.

Michael Bublé performed with a acapella group called Naturally 7.  They performed the Jackson 5 tune, "Who's Lovin' You" which he recorded for his new album, "To Be Loved."

Although this would be awesome to walk up to, I just got a laugh at all the people taping this performance on their phone.  I'm sure this thing blew up on Facebook and Twitter.

Don't you just love publicity stunts.  This was a good one.
