I chose this tune for many reasons—but first of all it just rocks! Secondly, it's a 24-bar blues, which is pretty unusual, so much so that I can't even think of another one! Like all of the tunes in this course, I definitely suggest that you listen to the original version.
Apart from the interesting length of the form, there are many excellent and extremely useful fills on each of the chords that we can steal and use elsewhere. I highly recommend categorizing them in your head so you can apply them to different situations. Right off the top, the first voicing we use is fairly open and can be seen as a Cm7 or a C7#9 chord (as the third is somewhat ambiguous). Right there we have something that we can steal and use elsewhere. Often times in the blues, the third is treated with a certain degree of ambiguity giving us what we hear as "bluesy." Make sure you pay close attention to the riff on the F7 chord as you'll want to nick that one!
