Guest Dave...you suggest >>>>>>take away the piano and the winterset are truly lost<<<<<<<...isn't that the same as saying..... take away the many guitars that folk singers use and they would be lost..... it seems irrelevant to me to make such a statement. They are the sum of their instrument(s) and talent which includes the piano.
If the drums had been taken away from the Beatles...I wonder if they would have done as well as they did?
