When I went to the concert, there were a number of firemen collecting money for two fallen comrades. I did not know what they were talking about since I had just come back from vacation and had missed all the news. But in todays Hamilton Spectator there is a sorrowful story that explains their reason for collecting.

I am very glad that GBS made a point of helping them all out.
