Most memorable spots for me...
The look on Vixen's face in Rick's accompaniment workshop when, after only a few minutes of instruction, she realized she was playing right along with him.

Hearing Darriel say, sometime around the time he was leading the Pub Sing workshop, "What's happening to me? I used to hate folkies. Now I am one."

Thinking something along the same line when I realized I was taking part in a song circle.

Being surprise at how many people made a point to introduce themselves to me, and how quickly I felt at home with so many.

Singing where someone else could hear for the first time since high school, and having the entire room join in singing rather than the entire room laughing at me.
