I have the original CD and listened on the AKG headphones and still don’t hear it.
I also had my wife’s healthcare worker listen on YT to Remastered version, nearfield, and she couldn’t hear it as a squeak. She is really big into jazz. We certainly heard other low level noises.
Maybe people are describing it differently, or maybe this is like the Emperor’s New Clothes...
Maybe it was one of the other tracks I remember hearing it on as a kid. There are several that are of a similar "groove." Maybe I’m going to have to listen to the early catalog on headphones to see if I can pick it out.
