take a close LOOK AT THE EVIDENCE

WHO PLAYED BASS ON SHE SAID SHE SAID? 

Paul McCartney stormed out of the recording session after arguing with John Lennon.
Did George play bass? Or did Paul record it before he left?

Rob is playing a 1985 Rickenbacker 4003 through a SansAmp VT Bass Deluxe.
His bass is strung with LaBella flatwound strings.
Music and lyrics by John Lennon and Paul McCartney
