This from Steve Redick:

This was quite the event. As I recall this was an arson fire set by a prostitute over a payment dispute. It could have been a disaster. Higgins was in the 1st Battalion and he always got the crazy incidents when he was working. You can hear Art Benker in the office, and also a brief appearance by “Brush Fire Bill” as the commissioner. I think I might have heard Bob Raicia (yes sir senator) in the mix as well….
