There is no singing ensemble with more experience than the Canadian Tenors. They have made multiple television appearances, including at the Emmys, the Vancouver Winter Olympics, and Windsor Castle, where they played for the Queen. It would have taken a lot to shock them in 2010, but Oprah pulled it off.

Although she had never met any of the band members, she had heard that they were all avid Celine Dion fans. They invited the renowned Canadian vocalist Leonard Cohen to join them on stage while they sang their biggest song, Hallelujah, on her show.

You have to wonder whether the band is plotting something when these kinds of things happen during concerts. That won’t happen! Their expressions of disbelief are priceless when Celine shows up. After a moment of disbelief, they resume singing, their expressions betraying their pure joy. Celine is so skilled that she effortlessly transitions into the role without any preparation, and their vocals harmonize exquisitely. It’s an absolutely remarkable performance.

It’s hardly surprising that the video has become an internet sensation. Its YouTube video has almost 20 million views. It was well-received by many: “These singers have my utmost respect, and what really stands out is the priceless quality of their unexpected reactions when they see Celine. It’s a testament to how much they cherish her and how much they respect each other.”

So, tell me about the tenors from Canada. Jill Ann Siemens, who won the International Song of Peace Award in 2004, created these. There were a few iterations from when they were a trio. A nationwide search led to the final selection of the long-term lineup. The quartet consisted of Clifton Murray, Remigio Pereira, Fraser Walters, and Victor Micallef.

The group inked a deal with Verve Records in 2012. Strictly Come Dancing was a smashing hit in 2013, and the band received the Queen Elizabeth II Diamond Jubilee medal that same year.

In the time after, they put out four studio albums, two of which were holiday albums. The fact that three of the albums peaked at #1 on the US classics chart instead of Canada’s is surprising. They have played at some incredible locations, including the Israeli Opera House, Carnegie Hall, and the Kennedy Center, and they are still touring.
