Here is the text of an apology issued by The Tenors after a lyric to O Canada was changed ahead of baseball's All-Star Game on Tuesday night:
"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."
