The latter plagued Tuesday's MLB All-Star Game early on, during a performance of Canada's national anthem.

It was only a week ago when we proposed that O Canada be replaced with The Maple Leaf Forever as the national anthem but Pereira's misdirected act was cruel and unusual punishment.

The group was supposed to sing: "With glowing hearts we see thee rise". But Pereira also held a paper-sized sign with "All Lives Matter" written on its back that shocked the American crowd when it appeared on the scoreboard's screen.

And just in case you missed the lyric changeup, Pereira held up a sign reading "All Lives Matter". "Of course "all lives matter" is a principle that we should all espouse ... but if we see that black people are being killed with impunity by police then you know that in our society, black lives don't, in fact, matter".

The award-winning group has previously performed at the 2010 Winter Olympics opening ceremonies, the Queen's Jubilee in England in 2012 and the 2014 Stanley Cup Finals.

The phrase "all lives matter" has stirred controversy as critics argue it undermines the Black Lives Matter movement.

The group blamed member Remigio Pereira for altering the lyrics.

TORONTO (AP) - The Tenors' rendition of O Canada at the baseball All-Star Game got Don Cherry's attention Wednesday as the hockey commentator slammed group member Remigio Pereira for embarrassing Canadians with his altered and politically charged lyrics.

"Oh well, all the left wing weirdos in this country are happy", Cherry said, although the "All Lives Matter" campaign is generally embraced by conservative Americans and not associated with left-of-centre politics.

Let the record show: neither version of those lyrics contains the phrase "all lives matter".

In its tweet, The Tenors called Pereira a "lone wolf" saying they were "deeply sorry for the disrespectful and misguided lack of judgement" he used.

Before the Major League Baseball all-star game in San Diego on Tuesday, Pereira changed a line in the Canadian national anthem to insert a political statement.

"I don't agree with black people dying". He said he wanted to, "speak for the human race and the lives of all sentient beings". Love, peace and harmony for ALL has always been my life's goal.

"Our honest apologies and regrets go out to everybody who witnesses this shameful act", the group wrote.
