The cover photograph was captured in a 10-minute shoot by Iain McMillan and only six pictures were taken. It sparked a conspiracy theory because Paul McCartney walked barefoot and out of step with Lennon, George Harrison and Ringo Starr. According to the theory, the album cover represented a funeral procession for the dead McCartney with Lennon dressed in white, as a clergyman, Starr in a black suit as an undertaker and Harrison in blue jeans, symbolising a grave digger.
