This was one of the songs in a fabulous recording session in 1974 titled "Soundstage - Chicago Blues Summit - 1974" and it was on TV last week. It's a treasure. Includes above 2 guys, and -- Pinetop Perkins, Junior Wells, Buddy Miles, Mike Bloomfield, Johnny Winters, and Dr. John. Willie Dixon wrote this song.
Muddy looks so serene and beautiful in these songs.
