First off: Cannot see the youtube link here.
So take anything I say here
with a grain of salt.
...never really considered the "Dry Cleaner from Des Moines" as walking bass
(it is a Funk'd-up Blues).
I'm thinking something more along the lines of "Rockin' in Rhythm" (from Night Passage
)...there be another example or two on Weather Report's final album w/ Jaco (Weather Report
) & any of the live Weather Report things with Jaco...it's been a long while since I tee'd up Standards Zone
(w/ Brian Melvin)...which is a piano Trio doin' Standards. I would think Jaco played some walking bass on that album, too.
