I'd guess we saw about 60 - we got there about halfway through a group, saw the next entire group, and left about halfway through the next. We were there long enough to be pretty impressed with the organization and a lot of the talent. Please thank April for being so nice to us!
Will do, DR Ginny.
Did you have any "favorites"? -Song titles only, please. 
I don't remember her song, but her acting part started, "Give up chocolate?!!!" And the girl whose blouse was the exact same color as the background drape - I felt so sorry for her and she blew me away with both her singing and acting.
It took me a minute to get used to the fact that the songs and speaking parts didn't go together. Karen, who's a high school teacher who teaches workshops on putting together auditions, explained a lot about the art and science behind the process. We were glad we'd been in the room before having lunch with her.
DR Ginny - I actually prefer it when the song and monologue don't go together, when they contrast. Most of the time, the "matching" packages come across as gimmicky to me. Additionally, some actors spend so much time trying to find the "perfect" song to go with the "perfect" monologue, that they end up using up all of their actual preparation and rehearsal time. However...
I have heard some pretty funny and callback-worthy audition packages over the years. One of my favorites which got "retired" a few years ago (when the actor became a full-time director) started off with a monologue about a doctor's exam. The actor/character is told he has to give a urine sample. He pulls/pulled a cup out of his jacket...
"How am I supposed to fill this up? Can you help me out, Jose?"
I play/ed his cue note. He starts singing...
"Soon it's gonna rain..."
