"Harmony Guy"
We run into this peep a lot. He's always singing harmony. Usually a third, but sometimes another interval. He generally harmonizes fairly nicely until the end of the phrase, where he typically goes off the rails. He never seems to notice, though.
"The Beat-boxer"
This peep will hang out near the band during soft instrumental music, providing the rhythm for those times when there either is no drummer, or the drummer isn't "pumping" enough for him.
