John, Paul, George and Ringo spent nearly a week at the town’s former RAF site in 1967, after being unable to hire any London film studios at short notice.
The movie, which was largely unscripted, used aircraft hangers for many of the scenes, including the ballroom sequence for Your Mother Should Know, while the video for I Am The Walrus was shot at two locations on the airfield, including atop the anti-blast concrete walls.
The race scene took place on the main runway and perimeter road.
The Fab Four also filmed in West Malling town centre, including the newsagents in the high street where Ringo can be seen buying tickets from John.
The building is now The Rain Grill kebab house, and has its own blue plaque to mark the historic event.
They had taken the long and winding road from Germany to Kings Hill, a journey of more than 450 miles, to visit the set of the famous film to coincide with the anniversary.
The commemorative tour was led by Simon Mitchell, who appeared in the film when he was seven, before his family moved abroad in 1977.
(PS – I did tours of the Beatles’ London for Simon and his group – lovely people and had a great time.
