Here are two versions of the same tune, separated by 26 years, with its composer performing on both. The first is the familiar 1965 version off of Rubber Soul with Sir Paul presiding on bass. The second is off of George Harrison’s 1991 live tour CD with Nathan East. Notice how the existing chord structure is re-emphasized by East, following the G chord in place of Paul’s pedal “A”.
