 I did not query him. As I told you before, I was into this. Walter Davis was since deceased. Hank Mobley was since deceased. I chatted with Franklin Skeet about it. He had nothing to impart. I chatted with Percy Heath, the bassist on the Charlie Parker version, and he was amused by the observance of the two keys but had no insight to why. He, again, is only on the Charlie Parker version in A-flat.
