With just days passing since the nation was gripped by the horrific terror attack at the Boston Marathon, residents are attempting to return to some semblance of normalcy. On the sports front, the Boston Bruins hosted the Buffalo Sabres for a hockey game at TD Garden tonight — an event that also offered up an extremely moving rendition of the national anthem.

Honoring the first responders who saved countless lives during Monday’s terror, the Huffington Post reports that the Boston Fire Department Honor Guard was on-hand. As is traditionally the case, before the game, a sole performer sang the beginning of the anthem. Rene Rancourt, a fixture at Bruins games, started the song and, before long, the entire stadium joined in.

Rather than a few sparse participants yelling words from the stands, the entire room boomed with the voices of men, women and children singing the familiar lyrics in unison. Rancourt lowered his mic so that the audience could be heard. As HuffPo notes, it was “an emotional moment for a city still reeling from recent tragedy.”

Here’s video of the touching National Anthem performance — a moving tribute to those who were lost and impacted by Monday’s violence:
