Well, the charts I have are someone else's notes, and although I've heard the song many times, I'm very inexperienced in jazz and wanted to get as familiar w/the song as possible. Of course Im seeing differences in interpretation in each version, so the consistent parts are what Im mostly listening for. And I've come to expect what some might call *harshness* over here- I can take(some of)it- when it gets to be too much I'll fill out a butthurt form, take my bass and go home.
Edit: Sometimes the root is not obvious(to me)- it helps to hear clearly what might work.
