At the first Boston Bruins hockey game after the bombing at the Boston marathon, the team did a special tribute.  They ran a special montage in honor of the first responders and those who were injured and to remember those who died.

But, things got extra emotional during the national anthem.  Rene Rancourt sings the Star Spangled Banner at every Boston Bruins home game.  He began to sing the song, but he didn't finish it.  Watch the video.
