A number of years ago I was playing in a nice restaurant and there was a couple that came in for dinner every Friday ... they sat at the bar near where I played and had dinner and would stick around listening for a couple of hours ... I asked if they had a favorite song, and this was it ... so the following week I put together a nice 'orchestration' on my technics kn6000, and played/sang it for them EVERY week ... they always said "thank you that was beautiful", but that was it - never a tip - ... but I made the 'thank you' be enough ...
I always admired the 'ease' at which Johnny Mathis sang ... and I remember hearing an interview with Anne Murray, and the interviewer said " singing comes so easy to you" and she responded "Are you kidding?, I'm working my a$$ off on that stage!" ...
