inclusion of "I'm Down" as one of the album's redeeming features. Rather than using the 18 June 1965 stereo mix, Martin remixed the song for the release from the original four-track tapes. The song has since appeared on the 1978 British compilation album Rarities, but was omitted from the 1980 US LP of the same name. Parlophone used Martin's 1976 stereo remix when they included the song on the compilation album Past Masters, Volume One, released on CD in March 1988. The mono mix was subsequently included on the Beatles' Mono Masters compilation. Writing for AllMusic, Stephen Thomas Erlewine calls the song "peerless" and that it demonstrated the Beatles' ability to "rock really, really hard". Ian MacDonald describes the song as an American rock-and-roll classic and a "demented raver" which illustrates the musical versatility of McCartney. Journalist Mark Hertsgaard calls the track "a wildly raucous rock 'n' roller" and "a rock 'n' roll raver, pure and simple", with McCartney's powerful vocal evoking "Long Tall Sally" while anticipating "Helter Skelter". Scholar Michael Frontani similarly compares McCartney's vocal to "Long Tall Sally", while also mentioning the "rock and roll shout" of his 1971 solo B-side "Oh Woman, Oh Why". Hertsgaard further praises the band's intense backing, singling out Lennon's organ contribution, which "all but literally [catches] fire". Barry Miles calls the song an "uptempo rocker", and Pollack calls it "raucous" and "rough-shod", with one of the most primal McCartney screams heard on a Lennon–McCartney original. Everett compares the song's style to both Little Richard and American rock and roll singer Larry Williams, and adds that the same style was later captured by the American rock band Creedence Clearwater Revival with their 1970 song "Travelin' Band". In 2011, the editors of Rolling Stone magazine ranked "I'm Down" at number 56 in their list of the "100 Greatest Beatles Songs". Other versions The Beatles live performances In August 1965, the Beatles purchased a new electric organ, a Vox Continental Mk I, using it for all subsequent performances of the song. The band regularly performed "I'm Down" during their 1965 and 1966 tours, incorporating it as their closing number. McCartney later recalled that it worked particularly well at large concert venues and was "a good stage song". The band's 15 August 1965 concert at Shea Stadium in New York City was filmed and became the centrepiece of the documentary film The Beatles at Shea Stadium,
