"[3] "Killing Floor" is an upbeat twelve-bar blues with an "instantly familiar" guitar riff provided by Sumlin.

[1] Backing Howlin' Wolf (vocals) and Sumlin (electric guitar) are Lafayette Leake (piano), Buddy Guy (acoustic guitar), Andrew "Blueblood" McMahon (bass), Sam Lay (drums), Arnold Rogers (tenor sax), and Donald Hankins (baritone sax).

[5] Shortly after arriving in England in September 1966, Hendrix performed the song when he sat in with Cream at Regent Street Polytechnic.

Other lyrics, notably "squeeze (my lemon) till the juice runs down my leg," can be traced to Robert Johnson's "Travelling Riverside Blues".

Though the amount was not disclosed, Howlin' Wolf received a check for US$45,123 from Arc Music immediately following the suit, and subsequent releases included a co-songwriter credit for him.

A version of "The Lemon Song" performed by Page and the Black Crowes can be found on the album Live at the Greek.

[15] According to Jean-Michel Guesdon and Philippe Margotin:[6] Slash performed a cover of the song with Brian Johnson of AC/DC on vocals and Steven Tyler of Aerosmith on harmonica on his 2024 album Orgy of the Damned.
