Thornbury Playing Fields, Bridge Rd. Isleworth, Middlesex and Studio Two, EMI Studios, London
The aerial shots of the Beatles cavorting on a helicopter launch/landing pad to the tune of "Can't Buy Me Love", filmed at Gatwick Airport South on March 13, were consiered insufficient for this sequence, so Richard Lester had the Beatles congregate early this morning at Thornbury Playing Fields in Isleworth, near London Airport, for some more filming, done at ground-level this time and on a fake helicopter pad constructed in four pieces. The Beatles ran about and played the fool as before, and Lester also had John, Paul and George jump off a ladder, filmed by a cameraman laying on the ground, to give viewers the impression of high-altitude leaping.
Later in the morning John had to leave Isleworth to attend a literary luncheon being held in his honour at the Dorchester Hotel, so the final items of shooting took place without him. (This is why only Paul, George and Ringo appear at the very end of the "Can't Buy Me Love" sequence, when a groundsman shouts at them "I suppose you know this is private property" and George sarcastically responds, "Sorry we hurt your field, mister".)
Filming at Isleworth ended at 1:00 pm so it's possible that any or even all of the Beatles attended a 4:30-5:45 mix session at Abbey Road, which resulted in another mono version of "A Hard Day's Night", this one for record release.
