Yellow Submarine

Should we thank the Beatles for drugs or the drugs for the Beatles? Somehow in 1968 both collided and out sprawled the psychedelic head-trip (that is supposedly for kids) known as Yellow Submarine. Captain Fred...yes, Fred...asks the Beatles to save his beloved Pepperland from the Blue Meanies. The Blue Meanies hate music, so the Beatles are there to save them. How? Thats a damn good question. Play music and drive them away is all I can assume happens because the whole thing is about as straightforward and sensible as an Escher drawing.
