I like this one, I have been guilty in the past of just learning the notes to songs without understanding the chord changes that are happening.

A good starting place to learning how the chicken 'works' harmonically is to play the chord tones of each chord (root, third, fifth and seventh) as they cycle along through the song. If you do that, your ear will get a fix on many of the notes in the bass line (particularly the third, fifth and flattened seventh) that jaco plays over the changes which (I think) are all dominant 7th chords.
A looping pedal is (I recommend the TC ditto) so useful in this respect.
It's a great tune...
