Sir Paul McCartney, 1t 63, has just completed his Got Back tour of North America. But at the 60th anniversary of Rubber Soul, it's good to look back at how that album marked a turning point in his approach to his primary instrument: the bass. Paul was an innovator, taking its use where no one in pop/rock had ever gone before.
