Last Tuesday, the Toronto Maple Leafs were taking on the Nashville Predators at the Air Canada Centre in Toronto. When Michelle Madeira’s microphone failed during the singing of the American national anthem, without missing a beat, the home fans stepped in and sang the rest of the The Star-Spangled Banner. Posted on YouTube, the video has now been viewed over 1.3 million times. Leaf’s fans are reciprocating the goodwill shown by the Pittsburgh Penguins who played the Canadian national anthem following the recent Parliament Hill shooting. The Penguins were playing against another American team, the Philadelphia Flyers – a game, O Canada would not have typically been heard.
