 Backing Wolf on vocals are longtime accompanist Hubert Sumlin on guitar, relative newcomer Freddie Robinson on second guitar, and Chess recording veterans Otis Spann on piano, Fred Below on drums, and Dixon on double-bass.It has been suggested that Freddie King contributed the second guitar on "Spoonful", but both Sumlin and Robinson insist it was Robinson.In 1962, the song was included on Wolf's second compilation album for Chess, "Howlin' Wolf".
