There are times when we may get a surprise and we never even see it coming. These are the moments that mean a lot to us, and they mean a lot to those who watch it when it happens to someone famous.

One famous group that understands the power of a surprise is The Canadian Tenors. As an experienced group of singers, they have been on television numerous times and performed at the Winter Olympics in Vancouver, for the Queen at Windsor Castle, and even at the Emmys.

You would think that it would take a lot to surprise The Canadian Tenors, but that isn’t the case. In fact, it took Oprah to surprise them in 2010, and the video is still going viral.

When Oprah looked into it, she found out that the group was a big fan of Celine Dion. Despite the fact that they are also famous, they never had an opportunity to meet her.

When they were on the Oprah Winfrey Show, they were performing one of their biggest hits, Leonard Cohen’s Hallelujah. It was a wonderful performance but it got better when someone surprised them by walking out onto the stage to sing with them.

It was none other than Celine Dion, and you could see the genuine look of shock and surprise on the face of the band. At first, they didn’t even know what to do but after a brief greeting, they continued with the song and it was pure perfection.

This is a video that has been viral and viewed more than 20 million times on YouTube. It seems as if everybody who watches it loves it, and you can see why by watching it as well.
