Manish Boy’ was one of a series of Chess singles that featured Muddy Waters convincingly touting his own virility (‘spelled M-A-N, that represent man, no B-O-Y’) ably (and verbally) assisted by an all-star crew with Junior Wells filling the harmonica spot usually held by Little Walter on Muddy’s sessions. It was a solid stop-time followup to Muddy’s ‘I’m Your Hoochie Coochie Man’ and Bo Diddley’s 1955 hit ‘I’m a Man.’ The original composer credits for ‘Manish (later also spelled ‘Mannish’) Boy’ went to Muddy, Ellas McDaniel (Bo Diddley) and a young Chicago songwriter, Mel London, who ran several blues labels in subsequent years. The record hit the Top Ten in all three of the R&B charts Billboard magazine then published: Best Sellers in Stores, Most Played in Juke Boxes, and Most Played by Jockeys.
