Paul McCartney is without a doubt one of the most important bassists of all time, people often overlook that.
He along with other bassists from that time like John Entwistle, John Paul Jones, Chris Squire, Phil Lesh and Jack Bruce were very important in giving bassists a more important role in a rock band, they didn't have to be just the guy in the background, they could play a very significant part in the music.
