... yeah, there was that time of The Beatles. A lyrical moment of humanity. "Last night I saw you in the restaurant. That's when I knew you were no debutant." Great guitar stuff, harmonies, you name it. All done with great style, purely natural. Hey, they were The Beatles; they could be as natural as they wanted to, they could be themselves. And, recognizing the beauty of the bargain, they were nice, and not only nice but deep, touching, poetic. Worth study. An accomplishment of humanity, in a mode dating back to a bardic tradition.
And then came a time of contention, or rather, The Time of Contention. Or that's what it always is. People being contentious.
