Here is my two cents worth and it is probably over priced at that. But I believe that MOST people who show up at a dance have very little interest in the musicians per se. They are more interested in whether or not they can move their feet in a way that is comfortable with the rhythm pattern of any given song. I believe that this theory applies to women more than men, and I don't mean that in any negative way. I just think that women are wired differently than men in many ways. It is my contention that just as the majority of men (young ones anyway) have an intense sex drive to the point that it is more important than food or water, so I think women (in general) have that same intensity of desire to DANCE. When you look out at the audience at a dance, you can be sure that the women are there to DANCE, whereas I think most of the men are there either to find a woman or to try to please the woman they are with. And I don't believe that either gender knows much about music. I bet if you polled the average audience at a dance, 50% can't carry a tune; 80% don't know the difference between a "regular" guitar and a bass guitar; 99% would not know it if you played a minor chord where you are supposed to play a diminished chord, and on and on.
Remember when Dick Clark had the "American Bandstand" show and he would ask people in the audience how they rated various musical groups? Did you ever hear one of them say "I didn't like the chord structure of that song" ? Heck no, the ONLY response you EVER heard was "IT HAD A GOOD BEAT" (if they liked the song) and "IT DIDN'T HAVE A GOOD BEAT" (if they didn't like the song)
So I guess that the bottom line is this. If you want to please the audience when you play, it is best to try to figure out what THEY think are the most danceable tunes. That idea is very hard to put in practice, at least for me. I prefer to play what makes me happy musically, but I know that is not always the choice of the audience.
Sorry, I got carried away.
