I'm not a guy who curses very much in my personal life. When I curse it sounds like a kid trying to be cool. But I think there are quite a few people, my father being one of them, who use curse words rather eloquently.
I always felt, as a listener at a show, that when there was too much banter between the artist and the audience that it detracted from the show. I more enjoyed shows where the guys came out and they just played.
