LONDON (AP) — It was 50 years ago today, that The Beatles caused a traffic delay.

And hundreds of fans of the Fab Four gathered at a crosswalk in London's St. John's Wood neighborhood Thursday to recreate the "Abbey Road" cover shot, half a century after it was shot.

Spectators snapped photos on cellphones as Beatles lookalikes crossed the street outside Abbey Road Studios in tribute to the original image.

At 11:35 a.m. on Aug. 8, 1969, Iain MacMillan photographed John, Paul, George and Ringo striding across the black-and-white "zebra" crossing while a police officer stopped traffic.

Used as the cover of the band's penultimate studio album, it became one of the most famous images in music history.
