Okay, so I finally got around to trying to glean the actual changes to this tune. It's pretty close to what was posted before. But, there are some differences.
Now, I got this from a live recording. So, I still haven't had the chance to compare to the studio version.

So, I've already been improving over these changes and have some ideas. But, what would you do with it?

Here's some of it to work with:

Still unsure on the "Vamp". I think Cm to Gm. But, I also hear Cm to G. So, I'll keep listening to it. Anyone else hear this better?



For the Solo Sections, there are a lot of options!

One that I've been using, is a mix of 2 Scales. The C Blues Scale, and the Em Pentatonic. Kind of mixing them up, and moving freely between them. If you try it, please let me know if they worked for you.

Man, this is a fun song to play!

As soon as the chords start going by, everyone who has heard it immediately asks, "what's that?" And every player has said, "Hey, show me that one!"

Pretty interesting voice leading and improvisational options, here.
