Yellow Submarine - Bass Line Video

The bass line on "Yellow Submarine" from Revolver (1966) is fairly straightforward, but does feature some nice moments. 

The passage after the lyric "And the band begins to play" is a little unusual. The backing track of guitar and bass continue with the regular chord progression - Am-C-D7. The brass ensemble, however, comes in playing a different chord (essentially just playing figure suggesting a G major triad). I had never actually noticed this discrepancy until I transcribed the bass line. 

I am playing a 1985 Rickenbacker 4003 through a SansAmp VT Bass Deluxe. My bass is strung with LaBella flatwound strings.
