Buffalo fans finish 'O Canada' after mic fails before Game 5 of Sabres-Bruins series

Fans at KeyBank Center carried "O Canada" after a microphone failed before the Buffalo Sabres and Boston Bruins played Game 5 of their first-round playoff series Tuesday night.

Cami Clune's microphone cut out early, and the crowd joined in to help finish the Canadian anthem before the singer returned with a new mic to perform "The Star-Spangled Banner."

She later said on social media it was a "crazy but cool moment" and thanked fans for singing along.

Buffalo is the only NHL team to play both national anthems before home games, regardless of opponent, a tradition tied to its proximity — about eight kilometres — to the border and a strong Canadian fan base.
