This is the album version, not the single. The two versions are essentially the same bass line. The primary difference is in the length of certain notes (e.g. half note vs. quarter note).
Rob is playing a Hofner HCT 500/1 through a Sansamp Bass VT Deluxe. His bass is strung with LaBella flatwound strings.
Music and lyrics by John Lennon and Paul McCartney
