SAN DIEGO -- During their performance of the Canadian national anthem prior to Tuesday night's MLB All-Star Game in San Diego, a singer in a group of tenors from British Columbia, Canada altered the lyrics of the anthem to include a reference to "all lives matter."

That member of the group, later identified as Remigio Pereira by the group, also held up a sign during the performance that read, "All Lives Matter."

Per the Score, Pereira replaced the lyric "with glowing hearts we see thee rise/the True North strong and free" with "we're all brothers and sisters/all lives matter to the brave."

The group issued an apology on Twitter later in the evening:

The Tenors are deeply sorry for the disrespectful and misguided lack of judgment by one member of the group acting as a "lone wolf" today during the singing of the Canadian national anthem at the Major League Baseball All-Star Game in San Diego.

The other members of the group are shocked and embarrassed by the actions of Remigio Pereira, who changed the lyrics of our treasured anthem and used this coveted platform to serve his own political views.

Our sincere apologies and regrets go out to everybody who witnessed this shameful act, to our fellow Canadians, to Major League Baseball, to our friends, families, fans and to all those affected.

The actions of one member of this group were extremely selfish, and he will not be performing with The Tenors until further notice.

All Lives Matter is of course a counterpoint of sorts to the Black Lives Matter movement, which has again been prominent in the news cycle of late. Needless to say, the Pereira's decision not only to make a politically charged statement at the All-Star Game but also to alter the lyrics of their country's national anthem figures to be quite controversial.
