The following video features a wonderful vocal quartet called The Tenors that was previously known as the Canadian Tenors. They were invited in a special televised concert where they sang a haunting rendition of hallelujah and left the entire audience in a trance. They are really good at what they do and you will no doubt love hearing more from them.

What this group was not expecting during their concert was the cameo of a special guest. Celine Dion walked out when they were singing and joined them on their song. All of them are so engrossed in their music that they don’t even notice her till later. And when they finally do, their reactions are priceless! They looked honored to have her with them and continue their performance along with Celine.
