Uncle Boko, why on earth shouldn't anyone make up their own rules about what they sing and when? I don't think anyone here has said what others ought to do; what people are saying is what they prefer to sing and to hear, and what works for them. There wouldn't be much point in the original question if all answers were ruled out of order.

You seem to have your own rules too: your rule seems to be that you'll sing anything at any time, regardless of its seasonality. You've also hinted at a preference for instrumentation over unaccompanied song. That's your choice and preference. Others have different priorities, and I'm finding it interesting to read and compare them. Most people who sings with or perform to others are interested to know what others enjoy, and why. If you don't think that's important, it's not worth reading this thread.
