SAN DIEGO — In a bold and potentially controversial decision that went largely unnoticed by the All-Star Game crowd, Canadian vocal quartet The Tenors altered the lyrics to “O Canada” to include the phrase “All Lives Matter.”

From the sounds of the video above, the group substituted the line, “We’re all brothers and sisters, all lives matter to the great” in for “With glowing hearts we see thee rise, the True North strong and free” before switching to French for the next line of the anthem. One member of the group held up a handwritten All Lives Matter sign during the performance.

The phrase “All Lives Matter” gained notoriety as a misguided response to the Black Lives Matter movement, but critics of the term have pointed out that it undermines the Black Lives Matter group’s efforts to reverse the longstanding history of mistreatment of African-Americans in the United States.

Update: The Tenors apologized for the “shameful act” in a press release, insisting it came due to the rogue actions of singer Remigio Pereira and did not represent the beliefs of the group. Pereira has been suspended from The Tenors:

So there’s that.
