"You Can't Do That" is a song written by John Lennon (credited to Lennon–McCartney) and released by the English rock band the Beatles as the B-side of their sixth British single "Can't Buy Me Love". It was later released on their third UK album A Hard Day's Night (1964). A live rendition of the song was released on the 2016 re-release of The Beatles at the Hollywood Bowl. Composition One of Lennon's semi-autobiographical songs, "You Can't Do That" "contradicted the genial tone with its tense threats, sexual paranoia and nagging, dragging groove", wrote Robert Sandall. The song's theme of jealousy was revisited in other Lennon compositions, such as "Run for Your Life" and "Jealous Guy". Influenced by the then relatively unknown Wilson Pickett, it is rooted in the twelve-bar blues form, with Lennon introducing a discordant sharp 9th (F) on the D7th chord, pointedly emphasising "…I told you before…" and then pushing this note for the exasperated "Oh!" before resolving to the song's key of G. Lennon also composed and played the guitar solo. The work reflected Lennon's love for hard-edged American R&B—"a cowbell going four in the bar and the chord going chatoong!" as he put it. George Harrison wrote the intro and outro guitar riff in the studio, according to Tom Petty in Rolling Stone. When asked by Petty how he came up with it, Harrison recalled "I was just standing there [in the studio] and thought, 'I've got to do something!'". With filming due to begin on A Hard Day's Night, film director Richard Lester needed the Beatles to provide him with original material ahead of production; "You Can't Do That" was selected to be part of the Scala Theatre "live performance" scene in the film, but was dropped from the final cut along with "I'll Cry Instead" and "I Call Your Name". The recording took nine takes to complete, and was considered for the A-side of their next single until McCartney wrote "Can't Buy Me Love". Recording and release "You Can't Do That" was recorded on Tuesday, 25 February 1964, in EMI Studios in London. An early take with a guide vocal is included on Anthology 1. It was the first song completed in the week before the Beatles began filming A Hard Day's Night, though "I Should Have Known Better" and "And I Love Her" were also started on the same day.
