<HTML>As a matter of fact, you really do have to make it right, because if you don't, the "monster" surprise piano player will show up and you will be the one with egg on your face.  Don't ever leave a piano less than you are capable of, its not true that the audience will probably not hear it anyway......You, the artist, and the entire crowd will definately hear it if it's not right.  Do it right and you won't have any worries or anxiety. tm</HTML>
