Even more excitingly for Beatles fans, McCartney is wearing sandals in the picture. In the famous version of the photograph, McCartney is seen in bare feet and out of step with the rest of the band. This has prompted a series of bizarre conspiracy theories among some enthusiasts who believe that McCartney actually died in the Sixties and has been replaced by a body double. They see the album cover as filled with hidden clues – with McCartney’s bare feet representing his difference from the rest of the band.
