That's my point - if you're not aiming to please your audience - to entertain them - then why perform in public at all, unless it's for entirely selfish reasons

The main club I go to is about 70% singarounds to 30% guest+floor spots. I don't regard myself as a particurally good singer - I don't do the more formal floor spots when we have them, for example - and while I certainly hope that I don't displease the other people, my main motivation is that I regard singing something as a sort of 'fee' for attending, which contributes to the club keeping going. Whether that is 'entirely selfish' I will leave for others to decide.
