Another Perfect Day For The Blues

I get these a lot for some reason.  The sort of day no goddamned good for anything except playing the blues.

I call this the Sunnyland Blues because it takes certain liberties with the 12-bar Blues Form.  But it does so with authority, specifically that of Sunnyland Slim who used it to great effect.

In a 12-bar in A, one normally hears only A, D and E.  Listen carefully for the odd F and B that sneaks in there.
