Probably State’s rights....
This 1957 recording is a great jazz combo duo. They start together, Louis picks it up in the middle, then Ella picks it up, and they wrap it up together.
Its hard to imagine Ella doing a different approach, but in this 1958 recording she does a big band version of the song.
