Going by McGrath's remarks to Ehrlich, this episode takes place around mid-March, which is very close to the original airdate.
Barbara: (after shooting stereo playing music) I hate rock and roll!!
Craig: What do you want?
Craig: He did a good job today, Ehrlich.
Westphall: Yeah. He seemed to handle himself very well.
Craig: He really measured up to the situation. You know, I'm tough on him day in, day out. And God knows, everything about him grates like sandpaper; the hair, the clothes, the lingo... But he really came through today. I think I'll keep on cracking the whip.
David Morse does not appear in this episode.
Episode Title: Dog Day Hospital
The title is a tip of the hat to the 1975 movie "Dog Day Afternoon" starring Al Pacino and directed by Sidney Lumet. Like the episode, the movie deals with a high risk hostage taking.
