If I remember correctly, the biggest thing about that game was the return of Bobby Orr (between periods) to the Boston Garden for the raising of his # 4 to the rafters. Someone posted a five part youtube of this -- I've posted the one below where Orr is given a Boston Bruins Jersey with his old # 4 on it and the crowd begs him to put it on one final time, for at this point he was still under contract with the Chicago Blackhawks.
The other segments of the retirement festivities show Orr getting something like a 10 minute plus standing O, essentially forcing them to cancel the other speakers, because people wouldn't stop clapping for Orr...
I'm still clapping....
