concludes with guitar-amplifier feedback, which Beck described in the Truth liner notes: "Last note of song is my guitar being sick – well so would you if I smashed your guts for 2:28". Power adds, "Jeff's solo at the end of 'You Shook Me' indeed lived up to his claim, vomiting all over Rod's shoes at the conclusion." For the recording, studio session musician John Paul Jones (who played bass on "Beck's Bolero" and the Yardbirds' "Happenings Ten Years Time Ago") contributed an organ part, which he would do later for Led Zeppelin's version. Although Columbia distributed a promotional 45 rpm "demonstration record" of "You Shook Me", a single was not released to the general public. The song is included on Truth and several Jeff Beck compilations. Led Zeppelin version English rock band Led Zeppelin recorded "You Shook Me" for their 1969 debut album Led Zeppelin. AllMusic critic Bill Janovitz describes it as "a heavy, pummeling bit of post-psychedelic blues-rock, with healthy doses of vocal histrionics from Robert Plant and guitar fireworks from Jimmy Page". At nearly six and a half minutes, it is considerably longer than the Muddy Waters or Jeff Beck recordings. Except for the breaks during the song's guitar solo, Led Zeppelin uses a straightforward twelve-bar blues arrangement, but performed at a slower tempo. During the opening and closing vocal sections, Page takes Earl Hooker's slide-guitar lines and stretches them out using liberal amounts of guitar effects, with Robert Plant's vocal matching them note for note. Plant uses Willie Dixon's opening verses, but also incorporates some from Robert Johnson's "Stones in My Passway": "I have a bird that whistles and I have birds that sings". The instrumental part consists of three twelve-bar sections for solos by John Paul Jones on organ, Plant on harmonica, and Page on guitar. Led Zeppelin biographer Keith Shadwick notes that, while the accompaniment may appear casual, it is "very tightly arranged, even down to [drummer John] Bonham's strict limitation of his cymbals to a ride splash in each bar and hi-hat beats in unison with his bass-drum pedal". Through the use of overdubs, Jones plays organ (using the pedals for bass) and electric piano. Led Zeppelin regularly performed "You Shook Me" during their concert tours until October 1969, and occasionally thereafter when the group began to incorporate more material from subsequent albums into their on-stage performances. Two versions from 1969 are included
