For you nocturnal types: “Back Door Man” from The Doors (1967)

In his own way, for a very different audience, Jim Morrison swaggered almost as convincingly as Howlin’ Wolf. The Doors actually gave credit where it was due on the record, to songwriters Willie Dixon and the mighty Wolf, aka Chester Burnett. (Too often in those days, rock and roll bands simply stole the great blues songs.)

You’ve gotta love the music appreciation notes in Wikipedia:

The promiscuous “back-door man” is a standard theme found in many blues, including those by Charley Patton, Lightnin’ Hopkins, Blind Willie McTell and Sara Martin. “Every sensible woman got a back-door man,” Martin wrote in “Strange Loving Blues” (1925).
