If all that has happened in the last few days haven't got you all emotional, this surely will. A guy named Rene Rancourt has performed the National Anthem at Boston Bruins games for the past 37 years. At last night's game he didn't get to finish the song.

Why? The crowd did it for him.

After singing a few lines the crowd jumped in and were so over-powering that Rancourt let them sing.

By the way, the crowd was already emotional because a montage of scenes from the marathon was just played on the jumbo screen.

(Rene Rancourt begins singing at the :29 mark and the crowd takes over at the :43 mark.)
