thank you! Most of that makes sense, and really emphasizes how much work (and effect) is in the post-recording part of making an album.

The re-mixing idea makes sense generally, but I understand that at least one song on the white album was performed at different speeds mono vs. stereo, and there are different sound effects between the two. If that's true, then it's not simply a matter of re-mixing from the same original tracks. But maybe there were only a couple of such examples?

Thanks again for the info!
