(this is in alphabetical order according to the notes i took in my program. the songs weren't listed and i'm not much of an expert so i don't really know what they all sang. sorry.)
Nancy Anderson was cute. i've seen her in Wonderful Town and A Tree Grows in Brooklyn, and i don't think the song (about meeting an optomitrist in the bookstore and having him read to her) fit her voice very well. she ended up sounding nasally and weird. but her comic timing is good and it was funny.
Bryan Batt was hilarious. He sang a song about a gay caveman and not only was the song really funny, he played it very well, complete with hand motions and facial expressions. really good.
Laura and Linda Benanti sang "No One is Alone" from Into the Woods, which i thought was a good choice. they sounded beautiful. and then the daughter (Laura, i think?) came back out later and sang a song she wrote for a friend about being a waitress, which was cute.
Nikki Renee Daniels and Max von Essen sang a great duet and then they each also did their own number, all of which were great. they have wonderful voices.
Randi Driscoll is like a recording artist who made a single to benefit the Matthew Shepard foundation. she played a cover of "Your Eyes" by Peter Gabriel and we all had to sing along. it was a weird juxtaposition with the rest of the broadway songs, but oh well.
Adam Fleming was adorable but looked and sounded really nervous.
Tom Hewitt was the closing number, which was well-sung and all, but it was slow and i thought a more upbeat number would have been a better ending to the evening.
Marc Kudisch sang a really funny song about how he did all these "gay" things but that he's straight. he's a great comedian.
JULIA MURNEY, emcee, was okay. i didn't like the song she picked AT ALL (at least that's what i wrote down, now for the life of me i can't remember what it was...she went like 3rd or 4th). but her voice is amazing and she's funny
Jai Rodriguez did a really bad duet with someone else on this list but i can't remember who. it was very unmemorable.
Emily Skinner has redeemed herself in my eyes. I didn't like her in A Tree Grows... because she had this awful brooklyn accent covering up her singing voice. but here she let it all come out and she was PHENOMENAL.
and of course, PATRICK, who wasn't listed on the program, *sniff sniff*, sang "Breeze off the River" from TFM. it was beautiful and made me cry. he was wearing the same old blue button-down shirt and jeans, which was odd since everyone else, audience included, was dressed up. but oh well
i can give more details on a specific person if anyone wants, but my memory sucks and there were a LOT of numbers.
