You have to mix it up.....play KB intros, create your own intros/endings, fade outs, jump from style to style on the fly, use Midi songs and play along or just sing, play mp3's backing tracks, play along, or just be a DJ.....what ever it takes ....remember if you play for people you are an "Entertainer First" NO MATTER HOW YOU DO IT. If the audience is happy with your performance you have done your job!

good luck
