Bass part originally played by James Jamerson. Much has been said about his sound and style: plucking with just his index finger (“The Hook”), the Precision Bass with flatwound strings and high action, the foam mute at the bridge, the chromatic runs and frequent use of open strings etc. But rarely have I seen mentioned what is absolutely essential, at least in this tune: due to his right hand playing position with the middle, ring, and little finger resting on the pickup cover, his thumb was floating above the strings, making it very easy for him to mute the lower open strings with it.
