Do you hoot and holler?
I have sometimes felt that our session was a little bit too serious, and could use some livening up—but then a fellow showed up who was just too disruptive with his random whooping and growling, and we had to ask him to go find another session. (Maybe he’s quieter when he’s sober—but I haven’t seen him that way yet, so I don’t know.)
So—at your sessions, do you do a lot of grunting and yelping, or do you just play the tunes? In our area, just playing seems to be the general rule.
