I do agree with you on most things you discussed except blackbird is an accidental masterpiece 😂 I heard Paul talking about it once and how the melody Was created From a classical piece by Yohann Sebastian Bach, that him and George used to play, very badly! Also, I believe the white album and Abbey Road to be exquisitely mixed and mastered. The guitar levels are very unique in certain songs, the level of clarity and harmony is incredible for the time. I agree that “Revolver” revolutionised music beyond doubt, but the Beatles (and George Martin)had progressed so much in terms of production quality and songwriting skill in their twilight years, it will never be matched in my humble opinion! All in all though, I enjoyed your analysis, cheers Arlie 👌🏻
