Things We Said Today is a song by The Beatles, written by McCartney and led on vocal by Paul McCartney. Within the catalogue, its introspective thread connects it to And I Love Her, Yesterday, For No One.
The session work falls within the band’s Beatlemania (1962–1964) period, recorded 2 Jun 1964 at EMI Studios, Abbey Road. George Martin produced; Norman Smith engineered. The song was recorded in three takes during the afternoon session. The first was a false start, the second was complete (vocals and rhythm), and the third saw Paul double-track his vocal, Ringo add a tambourine and John add piano. The recording sheets indicate that the piano was to be omitted from the remix, but because the piano had not been fully separated from the other instruments a little of its sound leaked across into the other microphones, so it can be heard on the finished song after all.
