Sorry to bump an old thread, but I noticed that no one reported from her tribute presented at the Gershwin, so I thought I'd share some aspects of my experience.
The stage was decorated with sunflowers, which provided a lovely juxtaposition with the Wicked set. LaChanze sang the first song of the afternoon.
Jason Danieley was a pillar of strength; he was emotional, of course, but was so focused on celebrating Marin's life, rather than fill the room with total sadness.
That said, when Terrence McNally gave his speech, there wasn't a dry eye in the joint.
It was so obvious how much Marin Mazzie was loved. I saw a number of luminaries in attendance: Barbara Walsh, Ann Harada, Liz Calloway, Victor Garber, Ashley Park, Alexandra Silber, Bebe Neuwirth. It was truly extraordinary to witness the community rally around this talented woman.
And for the record, she got a cancer society prize named after her, as well as a suggestion by one person (I don't remember who) to give her a posthumous Special Tony.
