I found this isolated bass track on YouTube.
Paul McCartney played his 1964 Hofner 500/1 bass with a pick on this wonderful George Harrison composition from the 1969 Abbey Road album.
I had a blast transcribing this melodic McCartney bass line, which is one of his finest moments. You can hear every single nuances & inflection in Paul's playing. So I was able to come up with a pretty accurate bass transcription/tab of Paul's performance. You can check out my transcription in standard notation & tab at http://playbasslines.com/
