Yeah, "Freddie" is a blantant 12-bar Blues.
"All Blues", though, has sort of a twist to it.
I've heard & played that tune so many ways...I'm gonna have to re-visit the original.
Or, maybe you can tell me

The tune does NOT go up to the 4 chord...right?
I agree totally on "So What" & "Impressions"...unless it was one of the rare nights when things just clicked, I was counting away. Even then, it was easy getting too caught up listening to a horn player or guitarist having their "rare night".
