You have the right standard, but you need to add a y-axis in order to reach an assessment. Of course (some) people on this board would come to NYC just to see all of these people (maybe except Broderick) but that is not nearly enough. What is the dimension of the audience? Note that many of the people you mention have been in shows that failed to find an audience (and that "of course" includes the one you say is an all-in-caps "of course").
I think by the way that it is almost always about the show and not the person. Even Jackman's demand softened after a few weeks last time (and that was at Circle!)
