The Beatles - A Day in The Life: April 27, 1965 (Tuesday)
Twickenham Film Studios, St. Margaret's, Twickenham
One of the most remarkable scenes in "HELP!" was that in which, heavily disguised, the Beatles are seen at an airport terminal (actually a film set, shot this day), prior to flying out to the Bahamas. It was remarkable because, as the years passed, three of the Beatles assumed his make-believe disguise in real life. With his long flowing beard and granny glasses, John was anticipating his summer-1969 look. Bewhiskered George looked this way again in Spring 1967 (Sgt. Pepper sleeve era) and Ringo's tight-cropped hair and thin beard was his mid-1970 image.
Also shot this day, preceding the imminent visit to Salisbury Plain, the Beatles filmed a scene with Ahme atop a tank turret.
