Choral 'Flash Mob' Hits Canadian Mall

Shoppers in one Canadian mall recently got more holiday spirit than they bargained for during lunchtime in a food court. What appeared to be a group of unassuming men and women eating lunch, turned out to be singers from Chorus Niagara, who dropped their burgers and burst into "Hallelujah."

The Canadian company, Alphabet Photography, came up with the idea as a thank you to its customers.  But the video quickly shot to the top of YouTube's charts, and has been viewed more than 15 million times. We speak to one of the singers, Stephanie Tritchew, who is now known around the world as the woman in the red scarf singing with her cell phone. Tritchew is a soprano studying at the University of Western Ontario.
