Noel, All I can add is that your playing was "something else!" Since I haven't listened to much of Tatum's actual work it's more reminiscent for me of Oscar Petersen who I used to study closely when he was on TV for the voicings used - not too successfully unfortunately!
Not just practice required - didn't you need to develop the paddle hands necessary to stretch for some of those open chords too? Fabulous.
