“The song has so much happening that when I casually listen I feel the accumulated effect, but attempting to really figure out what’s going on, I fear may take the fun out of it.” Nevertheless, Nicholas Dawidoff has a go at it, because it is, as he writes, “my idea of a perfect song. It is the epitome of The Beatles’ master building, of fitting stone upon stone, each section troweled together with such ingenuity and care that upon completion the whole thing feels seamless, a structure not built at all, but a whole that simply was.”
