Lennon's obvious response to McCartney's "Can't By Me Love", "You Can't Do That" was the first song recorded explicitly for use in the film A Hard Day's Night. Like his band mate's counterpart, it employs the 12 bar blues, but in G major (rather than the C major of "Can't Buy Me Love") to better suit Lennon's lower vocals.
On 24 February 1964, the Beatles recorded 9 takes (only 4 of which were complete) of "You Can't Do That".
Conspicuously absent from this sixth take are any non-lead vocals. Where the backing vocals were originally in "Can't Buy Me Love" but then removed before completion, the opposite is true of "You Can't Do That": By the time the song was completed, both McCartney and Harrison's vocals are heard.
Lastly, "You Can't Do That" is the first Beatles recording to feature Lennon playing lead guitar (lead was always played by Harrison up to that point).
