I love how the A section returns, a fourth lower. Are there any other GASB tunes that do that?

An interesting thread, the GASB is a great source for Jazz players, although we might
love BeBop, not all listeners are avid fans of it. but the Standards of which we speak
are familiar to most listeners with a good ear.
Having accumulated a large number of Real Books etc., I have a plethora of tunes to
choose from, most of which were great vocal songs but are ideal for players to improvise
upon eg., " I'm Glad There is You", The Folks who live on the Hill" ,My Foolish Heart"
"Speak Low", "Spring is Here" "Violets for your Furs" etc., almost ad infinitum
If they are unfamiliar to you , I suggest that you listen to some on YT if bored with
churning out the same old hacks.

If the key actually changes, it will be indicated in the score. There are tunes which actually change keys, and that is specifically written. But ATTYA doesn't actually change keys, it just seems to, although the key signature never changes. It's convenient to think of it as changing keys for soloing, but it stays in Ab for the entire song. And it doesn't go where it wants, it goes where Kern intended it to go. He had a plan and he executed it perfectly.

We don’t, however, mark each of those short modulations with a new key signature in the sheet music as that would be too distracting to the reader. We use accidentals instead knowing that these short “keys of the moment” will resolve back to the original key center.

There's no law that says a song almost everyone would say is clearly in Bb major can't be scored with a key signature of Ab major, or A major... you'd just have a wonky score, hard to read, full of accidentals.
From one perspective, the key is the key signature, whatever that might be on paper. From another perspective the key is really what almost everyone above says, and the score is wonky.
But those are extreme cases; in actual practice it is parts of the song that deviate. It might be that the turnaround goes from the tonic major chord to the two chord being a thirteenth, before it goes "back into key" by changing to minor. Or there might be a longer section that deviates from harmonization.
A single chord of the progression moving out of key for a second or two does not invoke a key change, and probably does not merit being considered as a key center shift or a re-assignment of "local key" or whatever... but a longer section might be thought of as having temporarily "moved".
People have varying degrees to which they can bear a deviation or departure from the original key before they begin having trouble maintaining connection back to the key and begin to want to grasp where they are more clearly within the new context of it being a new moved key from the original key.
