A vintage fashion car boot fair will turn the clock back to the Swinging Sixties when it returns to King’s Cross with a display of classic vehicles.

Rumour has it that a replica of George Harrison’s psychedelic Mini used in the 1967 Beatles film Magical Mystery Tour will be parked among the stalls — along with Mods riding in on their classic Lambretta scooters.

Harrison was the biggest petrolhead of them all back in the day - and loved fast cars and Formula 1 racing.

After a previous show in April, organiser, designer Wayne Hemingway is adding live entertainment and a ‘family fun’ zone with a fairground mini-ferris wheel and merry-go-round rides.

“There’s no cooler gathering in Europe,” Wayne insists. “We see London’s best-dressed vintage alternative crowd and a famous face or two coming to bag some unique second-hand finds.”

DJs are laying on vinyl selections. Broadcaster Katie Puckrik is joining the line-up to spin vinyl on the top deck of an iconic London Routemaster Bus.

A centenary display is being staged for the British motoring design pioneer William Morris, who created the classic MG in 1924. Morris set out to create a fast car with a sporty look which later became the choice for Hollywood movies — Elvis Presley used his own MG in Blue Hawaii in 1961.

Fans of American vintage cars are making a beeline to see a low rider, an original 1955 Cadillac Coupé which has been chopped to lower its roof and converted to ride on air bags and sit on the ground.

This market tends to attract stylish shoppers in their best threads and Mods and Rockers riding in on scooters and motorbikes throughout the day.

The King's Cross boot fair opens 10am to 6pm on Saturday and Sunday, September 28 and 29, at £6 entry in advance or £7 on the day. Kids under 12 and “well-behaved dogs” go free.
