While The Beatles were away on tour in Hong Kong, George Martin was at Abbey Road working on the mixes for the A Hard Day's Night LP.
He compiled two tapes containing the the mono mixes for the film soundtrack songs, for Capitol Records and United Artists to release on vinyl. There were eight songs on the tapes: I Should Have Known Better, If I Fell, Tell Me Why, And I Love Her, I'm Happy Just To Dance With You, I'll Cry Instead, Can't Buy Me Love and A Hard Day's Night. I'll Cry Instead was initially intended to be used in the film, but was left out of the final cut.
Two mono mixes were also made, of A Hard Day's Night and Things We Said Today. The mix of the title track was for United Artists, but solely for use in the film.
