Is There a Tier IV?

Al: I haven't met the conductor, but I've met the stage manager, who is also the timpanist.
Me: Ah. That gives me a lot of information right there.
Al: Yeah, that tells you where we are with this.

So many identities withheld, but most are guessable

IW: [good conductor] is coming tomorrow, to do kind of a conducting master class-y thing. With [bad conductor].
Me: Hold on. The worst conductor the chorus has had in the past ten years at least is going to have a coaching session with the best conductor the chorus has ever had? In front of the chorus?
IW: And it was [bad conductor]'s idea.
Me: Wow. That's...brave. I'm not sure it's going to work out as favorably for him as he thinks.
IW: I'm sure [good conductor] won't humiliate him too badly. Gay men have class.

Success!

Mike B: *whistling*
Matt: Great. Now that's stuck in my head, asshole.
Mike B: That worked better than I could have hoped.
