I agree with Mr. Gates above. I'm compiling a Beatles instrument spreadsheet and this song is a dilemma for me. Your logic makes sense up to Mr. Gates' point above. George would've had to play Paul's 1962 Hofner 500/1 bass upside-down. I play guitar/bass and I know it's possible, but is that really what they did for this song?? I love the detail in your website by the way. Very well done.
