Hi O-10 - as Frogman has tried a couple of times to explain to you, it is not the tune itself that sounds like elevator music. It is the cheesy string arrangement backing up the piano in that particular Previn recording that sounds like elevator. I guarantee you Previn himself performed it live in a much different fashion that would not have sounded like elevator music - probably many times, in many different versions, since he wrote the tune. That's the thing about jazz - it is never the same twice, even from the same performer, unless you are listening to a recording. Don't you remember that from your world class friend who lived with you that summer and never practiced who you heard perform a few times a week? I wonder what he really thought about your proud ignorance of music?
And no, of course the Ella performance of that tune does not sound like elevator music - your conclusion that I must think so because I thought the other one did is completely illogical. If you really cannot understand that, then it is truly hopeless to have any sort of intelligent conversation with you about jazz, let alone music in general; but I think you really do understand that, and are just pretending not to - so I am forced to wonder, as others have, why on earth did you start this thread when you are so resistant to anyone else's opinions? You should start a blog if you want the floor to yourself - this is an open forum.
