Senators fans helped out with "O Canada" after technical difficulties shut down the public-address system before Ottawa's game against the Vancouver Canucks at Canadian Tire Centre on Tuesday.
A fire alarm caused the PA system to shut down, and the teams took the pregame warmup without any music. A message on the scoreboard along with prompting from scheduled singer La Rochelle cued the fans to begin singing the national anthem.
La Rochelle's microphone began to work shortly after the song started, but she made sure to thank the Senators fans for a well-deserved assist.
