I have never posted this before, and just realized it! My deepest apologies! Its one of my very favorite pieces of music, originally written by jazz trumpeter Nat Adderley. My parents' band also played it. Everybody played it in the 60s, at some point.
As regular readers know, I loved the late, great Mr Mike Bloomfield, and his Chicago blues-guitar sounded just phenomenal here.
