I agree totaly, but the point i am making is that the piano player that got the rest of the tour was not as good as the others, he just had the "groove" that Chuck was looking for. With Chuck there is no rehearsal, you turn up and play live to the audience, that is the first time you get to feel what is required, one shot at it. The piano player that he used was no great technician like the others, he just found or had what was required by Chuck. Its that groove things again. Maybe the others if they had more time would have got through it, but time was not on their side. Again as has being mentioned, he was fit for pupose. Maybe he just had more experience, so kept it simple as he had heard what happened to the others, used their experience with Chuck to his benifit. It may even have been Chuck doing it to the piano players because he had the power to do so, proving a point to all around him that he's in charge?
