Good point Jim. I saw Poncho Sanchez in Lansing in a smallish concert venue, and he was obviously frustrated that people weren't dancing. He finally said, in effect, that they weren't going to play if we weren't going to dance. Well, we did, though it was a little awkward dancing in rows of seats.
I personally feel more relaxed when I'm not the sole focus of attention in a room, as long as someone there is digging it.
