During a pivotal playoff game between the Boston Bruins and Buffalo Sabres at KeyBank Center, an unexpected moment of unity unfolded. As Cami Clune, a former 'The Voice' finalist, began singing Canada's national anthem, 'O Canada,' her microphone failed.

Without hesitation, the thousands of hockey fans in attendance joined in, filling the arena with their voices. The collective singing became a heartwarming display of camaraderie and support, drawing praise from Clune and observers alike. Clune later expressed gratitude on social media, calling Buffalo fans the 'best fans ever.' This incident occurred before a game where the Sabres ultimately lost 2-1 to the Bruins, though Buffalo still leads the series.
