Excellent thread! I'm fortunate to be in a Beatles band and have the opportunity to play many of the songs mentioned in this thread whenever we perform. Playing these songs is such a blast and such a privilege. Listen to the entire Beatles catalog as time permits, as there is ALWAYS something to be learned. Paul was so ahead of his time and responsible for not only creating many of the most memorable basslines in recorded history, but also for implementing and using so many different techniques throughout the years which were typically not associated with bass players (chords, hammer-ons, slides, bends, pull-offs, etc.) These statements are sooooo true. A lot of people think what Paul plays is simple until you dive into it. +100 I completely agree. This is not one of the tunes that first comes to mind when you think of Paul's best basslines, but the way he weaves in and out of the verses and choruses is sheer perfection. It's not a standout bass line, but it fits the tune like a glove. +100 Hey Tony - Of course it's possible, but I doubt it. As far as I've read and understand, in the later years Paul would actually record his bass part last to really nail the story he wanted to tell within the song. Not sure if this is 100% accurate, but it certainly makes sense. Paul was also blown away with how the bass on Pet Sounds was almost never conventional and rarely was played as a root - the bass notes many times were not the note you'd expect, nor in the place you'd expect. This may have influenced his approach as well. We all know Paul had very little company when it came to creating melodic bass lines. SOOOOOO TRUE. Typical! Not taking anything away from all of the phenomenal bass playing through the years of of studio masters including Jamerson, Kaye, Osborn, Sklar, etc. However, I can't think of any other bassist in history who's bass lines can not only be recited by bass players, but can be recited by much of the general public as well. Truly amazing.
