Canadian hockey fans sang the "Star-Spangled Banner" at the second round of the Stanley Cup playoffs on Sunday when microphone malfunctions prevented the singer from being heard.
Country singer Brett Kissel was meant to sing the American national anthem before the Anaheim Ducks were to face off against the Edmonton Oilers for the third game of the second round of the Stanley Cup playoffs. Though he tried, Kissel's microphone would not work properly.
Kissel then led the crowd in a joint rendition of the song, with the Canadian fans taking over.
This is not the first time in hockey that fans have sung the national anthem of the opposing team's country. When a singer's mic cut out at a game in Toronto, the crowd instantly filled in and completed the song. At a later game, fans in Nashville sang "O Canada" as a tribute.
The Ducks won 6-3 on Sunday, but the Oilers are leading in the seven game series 2-1.
