I also feel even the strong left hand (piano) with drums is still not as pleasingly smoothly blended as a bass (especially acoustic upright) as the piano bass tends to sound a bit too harmonically complex for my ears. The string bass seems to be sonically more appropriate.

Tony, this tune has always been on my must play list, along with As Time Goes By and Somewhere Over the Rainbow...they seem to be loved and recognized by a broader age range of listeners than most tunes, especially if you are playing only instrumentals.

"All the Things You Are" is another one that seems to fit in with the above.

They are all so rewarding to play.
