"Mannish Boy" (or "Manish Boy" as it was first labeled) is a #bluesStandard written by #MuddyWaters, #MelLondon, and #BoDiddley (with Waters and Diddley being credited under their birth names). First recorded in 1955 by Waters, it serves as an "#answerSong" to Bo Diddley's "#ImAMan", which was in turn inspired by Waters' and #WillieDixon's "#HoochieCoochieMan". #MannishBoy features a repeating #stoptime figure on one chord throughout the song.
