I wasn't implying you'd thump them El Greko, just that they'd be be lacking in the ability to recognise good stuff.

One thing is that a song needs to be sung-in, generally, and that normally means sung a good few times in public, somit's best to spread trhta roud a bit.

And it's advisable to sandwich a new song in between songs you've already sung-in, and if possible after you've sung one people know and like hearing you sing (if they know you), so they trust you when you sing something they haven't heard before, and give the song a chance.
