Beatles fans being urged to share their memories of the day the Fab Four came to Chiswick .

John, Paul , George and Ringo visited Chiswick House on May 20 1966 to film promo videos for Paperback Writer and Rain.

Chiswick House and Gardens Trust is preparing to celebrate the 50th anniversary and wants to hear from people who were there that day.

Footage of the group miming to the songs in and around the 19th-century conservatory and 18th-century gardens was used to promote the Beatles here and in the US, making it the forerunner of the now ubiquitous music video.

Youngsters can be seen playing on the tree behind the band, schoolchildren in maroon uniforms are visible outside the conservatory, and adoring students are pressed up against the gates desperate for a glimpse of their idols.

Half a century later, Chiswick House's 65-acre grounds remain a site of pilgrimage for many Beatles fans.

"If you were there or recognise someone who was, the trust would love to hear from you for their archives and to celebrate the 50th anniversary of the visit of the four most famous people on the planet at that time," said Lucinda MacPherson, of the trust.

Anyone wishing to share their anecdotes or pictures from that day is asked to email archive@chgt.org.uk, putting 'Beatles Memories' in the subject field.

The Beatles were no strangers to west London, of course.

The iconic Abbey Road album cover was shot in St John's Wood , and they played their final gig on the rooftop of a building in Savile Row.
