Yeah, that makes sense.
We have a reputation of being unresponsive and perhaps even hostile at times, but a good question (want to build a leadsheet by transcribing from the best recordings of a standard) usually gets very good responses.
It's the same tired old, mal-conceived questions that on a good day we ignore and on a bad day we flame. Ironically those probably get a lot more uptake with the BGists.
Another thought, learn the lyrics if you don't know them. Ella is great, but I don't know if she's the best source of lyrical accuracy on this particular tune. Still, check her and others out for the lyrics. It'll help you when you play the head.
