[7] Lennon was reportedly dissatisfied with the Dakotas' arrangement of his song as well as its position as the single's B-side, so the Beatles recorded their own version.

[8] Since the song was being considered for inclusion in the Beatles' 1964 debut film A Hard Day's Night, a rush mono mix for United Artists was attempted on 3 March 1964, but was ultimately scrapped.

The final UK mono mix was performed on 4 June 1964, intended for the A Hard Day's Night LP, but ultimately appearing on the EP Long Tall Sally.

[9] The final UK stereo mix, performed on 22 June 1964, three days after the release of the Long Tall Sally EP, and also intended for the upcoming stereo version of the UK album, did not appear on a British release until the 1976 Rock 'n' Roll Music compilation (along with the remaining tracks from the Long Tall Sally EP).

The Beatles recorded the song for the BBC radio programme Saturday Club on 31 March 1964 (transmitted 4 April 1964).
