Why it sounds like that

Nathan Watts played bass on Sir Duke, and his bass was a 1974 P-Bass with Rotosound strings, recorded direct. The band rehearsed the song and then cut it live at Crystal Industries in Los Angeles. The bass has a unison line that is played with a bend up to the top fret, and the outro is where the bassist cut loose.
- Bend up the last fret to reach the highest note of the unison line.
- Cut loose a little on the outro.
