A large statement is made with The Beatles wearing vibrantly coloured military uniforms. This is actually mimicing the establishment. It defies and undermines the military ways. The bands actual positioning establishes their cult significance, in front of the many famous figures in the background.
Finally the actual background is a blue sky representing happiness; freedom; summer of love; exotic; peaceful; heaven; hope. And a palm tree that signifies the idea of an island, the band being untouchable, escaping the british norm and the sense of exotica.
