I'm confused, Tattie Bogle--the chords are very good, which is pretty unusually for an online jazz chart. If there seem to be way to many chords, it's easier if you recognize that a lot of the song is just the ii/V7 progression, which is basic jazz progression, only repeated in a number of keys(Dm7-G7,Gm7-C7, F#m7-B7, etc).

If you can play

Gm7-

3-x-3-3-3-x

C7-

3-x-2-3-3-x-

you can play all the different chords by moving up and down the neck. F#m7/B7 is on the 2nd fret,Dm7/G7 is on the Ninth, etc.

After that, just walk through the chord progression a few times without playing it in rhythm. Just brush the chord once and give yourself what ever time you need to get the next one. After you do that a few times, it will start to fall together.
