"Ebb looked like he was actually crying."
Which is weird. Liza's reaction is something you would expect from her. It's not really out of the ordinary. But Ebb acts like a teenage fanboy. How would he act if Gwen Verdon showed up?
And you barely see Dinah in that clip.
So it makes me curious what the situation was. Did Chita just drive over to Dinah's show and walk in and say "Hand me a microphone" and they really hadn't seen her in ten years?
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
