Rules are fine but I believe it really depends on the situation. I take exception with many I have read on this topic. No jokes, you're not funny? I don't know about anyone else's situation, but in the club, hip party scene you damn well better be funny. Club owners and clients pay big dollars at least around my area to have their patrons entertained. Talking, joking, interacting with them gets them involved. They feel like THEY also are part of the show. Inside jokes within the band? Been there too. If you build up a very loyal following, they too get the joke over time. Once again they feel involved. Same goes with talking to a patron between songs. If the front man or whomever is worth anything other than being a pupet, they can turn that interaction into a good bit that everyone can chuckle at. Personally, I did the serious route for many years. Played for huge crowds as well as intimate setting for record execs. Do the rules still apply? Sort of, IMHO. Of course you wouldn't go for the comedy thing in that situation. Entertainment parameters are not just black and white. One thing I have learned over the years. Don't take youself so seriously that it stops being fun. Did that too! Music is meant to be fun, at least for me. Life is too damned short to sweat the small stuff. How many times have you heard someone say "I'll stop doing this when it stops being fun"? I don't know about how others feel, but I never want to stop. Let the fun continue!
