What I really hate is when people come up and ask "Have you got (name of song) in there?" They assume everything is some sort of karaoke. Don't know if I should feel flattered that it sounds good or offended that they don't even know I'm playing.
I'm thinking of turning my rear end to the audience so they can see that I'm playing!
In the old piano bar days, I had a huge mirror behind me, tilted so people could watch my hands. Also, they were sitting right next to me as well.
