I really love this song and how it was recorded. Now what puzzles me is the multitrack setup. On the first multi-track aka takes 1-16, it's the basic track but was it only sent to one track or two? I know Brian did two Instrumental Inserts for other instruments, so did those take up tracks two and three and then it was bounced or did Brian record the basic on two tracks and then added the other instruments, so he had a full 4-track master which had to be bounced for vocals. I was playing around with a channel remover aka Vocal Trap and it indicates on the 1st insert that tracks one and two are basic with three being the acoustic guitar, organ and bass. Or am I hearing a ghost track? However, with this channel isolation, the middle channel is just occasional piano, drums, castanets and tambourine which sounds awesome, while the left channel is just guitar with some bleed from other instruments. I hope someone can clear this up! I have even spaced the two isolated basic parts and you can get some stereo separation, it's weird!
Here are the left and middle channels from the 1st instrumental insert spaced apart:
